Description

Finger positioning device for maintaining the level of nails for nail art

[0001] The present invention relates to a finger position adjustment device for maintaining the horizontality of nail art nails used in nail art treatment for printing images such as various shapes, figures, and letters in multiple colors on the surface of a user's nail, and more particularly, to a finger position adjustment device for maintaining the horizontality of nail art nails that allows the angle of the nail of a user of nail art treatment to be adjusted to maintain the optimal horizontal angle for printing nail art images based on image information provided from the user's nail.

[0002] As interest in beauty has rapidly increased due to the recent improvement in consumer living standards, interest in nail and toenail care has also been increasing.

[0003] This type of nail art (also known as “nail art”) involves not only painting the nail polish on the nail surface after trimming the area around the nail, including the nail itself, but also drawing shapes, figures, letters, etc. in various colors on the nail surface to give the nail an artistic look. It involves drawing pictures on long nails or attaching beads or jewels. It is particularly popular among young women, and has become widely established as a cosmetic trend from a temporary boom.

[0004] However, nail art has traditionally been a professional service provided by beauty salons, and the problem was that it took time to complete the nail art, and therefore the fees were high.

[0005] To solve this problem, various nail beauty techniques have been developed recently to solve this problem by directly printing nail art on the nails or attaching a sheet with nail art printed on it to the nails, examples of which include patent documents 1 to 6.

[0006] Patent Document 1 proposes an 'art seal automatic vending method and device, art seal sheet' that scans a user's fingernail image and prints it on a sheet to create an art seal, such as a nail seal or tattoo seal, that fits the user's fingernail perfectly and prints it on an image retention sheet.

[0007] Patent Document 2 describes a system for nail management, such as creating an object on a nail, comprising a shape information providing means, an object or design providing means, a management means, and a control means, wherein the shape information providing means typically scans the position and / or shape of the nail to provide first control data. The object providing means typically provides object data related to an object to be created to provide second control data. The management means is, for example, a 3D printer or a dispensing means, which creates an object on the nail, and the control means is used to control the operation of the management means based on the first and second control data to create a desired object on the nail to be managed.

[0008] Patent document 3 is 'providing a nail art device comprising: a fingertip fixing means for fixing a fingertip performing nail art; a plate conveying mechanism for conveying a carving plate; an ink nozzle receiving section for dropping ink next to a used plate surface on a carving plate conveyed by the plate conveying mechanism; a squeegee for applying the dropped ink to the plate surface; a pad for transferring the applied ink and then retransferring the transferred ink to the nail of the fingertip of the person receiving the treatment to print; and a plate surface cleaning unit for cleaning the carving plate (11) after use, thereby enabling images of various contents to be drawn on the nail with high precision using ink of various colors in a short period of time without causing a cumbersome task to the user, and also relatively less soiling of the surroundings of the device.'

[0009] According to patent document 4, it is disclosed that a nail art device is proposed, which has a printing means for printing a shape on a fingertip nail, a contour recognition means for recognizing the contour of the nail, a concavity recognition means for recognizing the concavity of the nail, and a three-dimensional display device for displaying the contour and shape of the recognized nail in three dimensions.

[0010] According to patent document 5, a nail art system capable of printing a specific image on the nails of a member visiting a store is disclosed, including a contact unit that detects the entry of a member's finger into the main body and contact with a fingerprint, one or more cameras that capture an image of the member's fingernail from the opposite direction when the contact unit detects contact with a fingerprint, an image acquisition device that captures a specific pattern provided by the member inside a nail area identified among the nail images captured by the camera and acquires image information of the pattern, a storage unit in which the image information acquired through the image acquisition device is edited and stored by a control unit, and a control unit that displays the nail image captured by the camera and confirms the nail area in the nail image where the specific pattern will be printed, while displaying the image information of the specific pattern acquired through the image acquisition device on a display device and printing the edited image information to be stored in the storage unit by placing it inside the nail area.

[0011] However, although the nail art devices of the above prior arts have in common the point that they print a desired image on the surface of the nail for the purpose of beautifying the nail, there is a concern that the quality of the nail art image expressed on the surface of the nail may be reduced.

[0012] That is, nail art devices like the above-described prior art can print a nail art image selected by the user onto the fingernails based on an image of the fingernails captured by a nail measuring device. However, each user's fingernails vary in appearance, and fingers have numerous joints and are highly mobile. Therefore, the shape of the fingernails can vary significantly depending on the direction and method of capture.

[0013] Therefore, when nail printing is performed on the nail area extracted from the data captured in this way, if the horizontal angle of the nail changes due to movement of the user's nail position, there is a problem in that the actual image printing is not performed accurately, such as printing beyond the boundary of the nail due to a discrepancy with the initially obtained data.

[0014] Therefore, in order to print nail art images at the exact location of the user's nails, there is an urgent need to develop a technology that can adjust the angle of the user's nails to maintain a horizontal angle that is optimal for printing nail art images.

[0060] As shown in the drawing (see FIG. 7), the finger rotation part (150) includes positive and negative rotation motors (M2) attached to one end (rear side as seen from FIG. 6) of the finger support member (113) positioned to rotate left and right on the base (114) among the finger support members (113), and the positive and negative rotation motors (M2) control the left and right rotation amount of the finger support member (113) on the upper surface of the base (114) according to a preset nail horizontal angle measurement signal of the nail measuring device (10) (see FIG. 3), thereby adjusting the nail horizontal angle of the corresponding finger to fall within the preset nail horizontal angle range of the nail measuring device (10) (see FIG. 3), thereby enabling the printer (20) (see FIG. 2) to print (process) accurate nail art on the surface of the user's nails.

[0061] The above nail measuring device (10) is a device for measuring the shape of a nail, and may be a camera or a 3D scanner for taking an image of a nail. The nail measuring device (10) determines the image-processed nail area and the horizontality of the nail based on the taken finger image, and provides information to a printer so that a nail image for nail art selected by the user can be printed on the user's nail.

[0062] An example of the operation of a finger position adjustment device for maintaining the horizontality of nails for nail art of the above configuration is described again with reference to the drawings.

[0063] <Location of the finger support part (110) of the user's fingers for nail art on the user's nails>

[0064] A user who wants to do nail art can first support the fingers of the left hand or the fingers of the right hand for nail art on the finger support member (113) having the finger support groove (111) of the finger support member (110) as shown in FIGS. 1 to 3. At this time, in order to ensure a stable position of the fingers, the wrist of the left or right hand is stably supported by the wrist support plate (103) and the fingers of the corresponding hand can be positioned on the finger support member (113) of the finger support member (110).

[0065] (a) and (b) of Fig. 8 show a case where the fingernails of the left hand and right hand are provided for nail art first. In the case where nail art is to be done on the fingernails of the left hand, as shown in (a) and (b) of Fig. 8, the remaining fingers of the left hand, excluding the thumb, such as the ring finger (little finger) (f1), ring finger (f2), middle finger (f3), and index finger (f4), are positioned in the order of the ring finger (little finger), ring finger, middle finger, and index finger on the corresponding finger supporters (113) as shown in (a) and (b) of Fig. 8, while only the thumb (f5) of the right hand is positioned on the thumb supporter (113-2) located on the right side of the finger supporter (110).

[0066] The ring finger (f1), ring finger (f2), middle finger (f3), and index finger (f4) to be placed on each corresponding support member are positioned accurately below the fixed band (115) so that the users can directly push their hands so that the corresponding fingers can be positioned inside the corresponding fixed band (115). At this time, the corresponding finger supports (113) of the ring finger (f1), ring finger, and index finger, excluding the middle finger and thumb supports (113-1, 113-2) in the finger support member (113) of the finger support part (110), are placed on the corresponding finger supports (113), and the pushing force of the hand applied to the corresponding support member (113) is applied together with the forward and backward moving plate (133-5) and the up and down and forward and backward moving bars (139) supporting the corresponding finger supports until the middle finger is inserted into the inside of the fixed band (115) of the corresponding support member as shown in FIGS. 4 to 6. By moving backwards along the guide grooves (137-1, 137-2) and the rail (133-3) while resisting the spring (138-1), the corresponding fingers (ring finger (little finger), ring finger, and index finger) can be positioned precisely inside the corresponding fixed band (115).

[0067] In the case where a user, unlike the above, wants to do nail art on the right finger first or wants to do nail art on the right finger after completing nail art on the left finger, the user should position the right finger in the order of the ring finger (little finger), ring finger, middle finger, and index finger, excluding the right thumb, on the finger support (110) of FIG. 8, in the opposite direction to the above, and position only the left thumb on the thumb support (113) located on the left side of the finger support (110).

[0068] The reason why the thumb supports are arranged on both sides of the finger supporters (113) of the above finger supporters (110) is to enable the free fingers of the left or right hand located on the left and right thumb supports to conveniently operate the switches of the switching units (SW1, SW2) arranged adjacent to the left and right thumb supports as seen in FIGS. 2 and 3.

[0069] <Fixing and releasing of the finger of the nail art user located on the finger support part (110) by the finger fixing and releasing part (130)>

[0070] Fixing the user's finger for nail art

[0071] The fingertips of the nail art user located on the finger support part (110) need to be firmly fixed with a fixing band (115) to prevent movement of the fingers in order to accurately apply nail art to the corresponding nails. For this reason, the user can fix or release the fingers located on the finger support groove (111) of the finger support member (113) of the finger support part (110) by controlling the forward and reverse movement of the forward and reverse motor (M1) by the switches (SW1, SW2) of the drive control part (130-2) (see FIG. 5). The control of the drive control part (130-2) (see FIG. 5) can be executed by operating the bar-shaped switches (SW1, SW2) that form the switching part (SW) of the drive control part (130-2) (see FIG. 5). For example, when the fingers of the left hand (the ring finger (little finger), ring finger, middle finger, and index finger) are provided for nail art, the fingers of the right hand, except for the thumb, are free, so the switch (SW1) arranged in the adjacent area and the right thumb support member (113-2) can be freely pressed and operated to control the forward or reverse motor (M1) of the drive control member (130-2) (see FIG. 5) in the forward or reverse direction. On the other hand, when the fingers of the right hand are provided for nail art, the switch (SW2) arranged in the adjacent area and the left thumb support member can be pressed and operated with the remaining free fingers of the left hand, where only the thumb is provided for nail art, to control the forward or reverse motor (M1) of the drive control member (130-2) (see FIG. 5) in the same manner as above.

[0072] Therefore, when the above push switch (SW1 or SW2) is operated, the current of the power supply (not shown) connected to the positive / negative motor (M1) is controlled to rotate the positive / negative motor (M1) in the forward direction, that is, in the direction of arrow a in Fig. 5. This positive / negative rotation of the positive / negative motor (M1) causes the operating cam (C) and the power interruption pivot plate (P), which are integrally connected to the drive shaft (S) of the positive / negative motor (M1), to rotate in the same direction as the positive / negative motor (M1).

[0073] The rotational movement of the above-described operating cam (C) causes the moving plate (134) that comes into contact with the operating cam (C) to move upwardly along the support angle (132). The upward movement of the moving plate (134) causes the finger (left and right thumb and middle finger) support member (113) connected to the moving plate (134) through the up and down movement bars (136), and the finger (ring finger (little finger), ring finger, and index finger) support member (113) connected to the moving plate (134) through the up and down and forward and backward movement bars (139) to move toward the fixed band (115). Accordingly, the fingers that were positioned on the finger (left and right thumb and middle finger) support member (113) come into contact with the fixed band (115) and are fixed in a state of being pinched by the finger support member (113) and the fixed band (115).

[0074] Maintaining this fixed state is performed by stopping the rotation of the positive / reverse motor (M1) that drives the operating cam (C). Stopping the rotation of the positive / reverse motor (M1) is performed by cutting off the power applied to the positive / reverse motor (M1) when the protruding end (P1) of the power-interrupting rotary plate (P) that rotates together with the operating cam (C) of the positive / reverse motor (M1) comes into contact with the power terminal (T2).

[0075] The forward driving stop of the above-described positive / negative motor (M1) keeps the user's fingers in a fixed state in cooperation with the fixed band (115). When the fixation of the fingers placed on the finger (left and right thumb and middle finger) support member (113) is confirmed, nail measurement is initiated by a conventional nail measuring device (10) previously installed above as shown in FIG. 3. When it is confirmed that the measured nail's horizontal state is within a preset horizontal range, the printer receiving this signal immediately performs a normal nail art task of precisely and accurately printing the image selected by the user on the surface of the user's nail. A case where the finger is twisted and the nail cannot be at a horizontal angle and this needs to be adjusted will be described later below.

[0076] Unlock user's finger after nail art is completed

[0077] When the printing of nail art is confirmed to be complete, the user must release his / her finger from the fixing band (115). The release of the finger can also be done by the user operating the switch, just like the fixing process described above.

[0078] Unlike the above embodiment, the re-operation (pressing operation) of the above push switch (SW1 or SW2) controls the power applied to the forward / reverse motor (M1) to rotate the forward / reverse motor (M1) in the reverse direction opposite to the direction of arrow a in FIG. 5. This reverse rotation of the forward / reverse motor (M1) causes the operating cam (C) of the forward / reverse motor (M1) and the power interruption pivot plate (P) to rotate in the same reverse direction as the forward / reverse motor (M1), and when the protruding end (P1) of the power interruption pivot plate (P) comes into contact with the power terminal (T1), the power applied to the forward / reverse motor (M1) is cut off, thereby stopping the reverse rotation of the forward / reverse motor (M1).

[0079] During the reverse rotation process of this reversible motor (M1), the reverse rotation movement of the operating cam (C) causes the operating cam (C) to move upward and separate from the moving plate body (134), which was pressurizing the moving plate body (134), thereby releasing the pressure from the operating cam. The release of the pressure on the moving plate (134) from the above-mentioned operating cam (C) is positioned so as to wrap around the circumference of the up-and-down moving bar (136) between the fixed plate (133) and the finger support (113), and each end is positioned so as to wrap around the circumference of the up-and-down and forward-and-backward moving bars (139) between the spring (135) fixed to the finger support (113) side and the fixed plate (133), and the support (113) and the forward-and-backward moving movable plate (133-5), and each end is positioned so as to wrap around the circumference of the up-and-down and forward-and-backward moving bars (139), and the spring (138) fixed to the finger support (113) side and the forward-and-backward moving movable plate (133-5) side, and the up-and-down moving bar (136) and the finger support (113), and the up-and-down and forward-and-backward moving bars (139) and the finger, which have been pushed upward by the moving plate (134) so ​​far, due to the elastic force of the spring (138) trying to return to the original position. The support member (113) is quickly moved to the lower position, which is the original position, thereby achieving a release state separated from the fixed band (115), and at the same time, the spring (138-1), which was maintaining a contracted state at the rear side of the movable plate (133-5), also has a restoring force to return to the original state, thereby causing the movable plate (133-5) and the up-and-down and forward-and-backward moving bars (139) to move together to the forward position, which is the original position, along the guide rail (133-3) and the guide grooves (137-1, 137-2) respectively (see FIG. 4), thereby enabling the nail art user to freely separate their fingers from the finger support member (133) and the fixed band (115).

[0080] The above finger fixation and release state can be repeatedly performed while the user is doing nail art on his or her fingernails, and in addition, the control method for rotating the forward or reverse motor (M1) of the control unit (130-2) (see FIG. 5) in the forward or reverse direction by controlling the current flow by pressing the push switch (SW1 or SW2) of the drive control unit (130-2) (see FIG. 5) can be generally adopted in various ways, so a description of only one in this embodiment is omitted.

[0081] <Maintaining the level of the nail art user's fingers by the finger rotation part (150)>

[0082] If the user's finger turns left or right, disrupting the level of the nail, the image may not be accurately printed on the nail, potentially leading to complaints from consumers. To prevent this, it is necessary to correct the angle of the user's finger to maintain the level of the nail.

[0083] In particular, among the fingers placed on the finger support member (113) of the finger support member (110), the ring finger (little finger), ring finger, and index finger, excluding the thumb and middle finger, are most prone to being twisted to one side due to the nature of the fingers. Therefore, it is necessary to maintain the horizontality of these fingers. For this reason, in the present invention, the finger rotation member (150) that maintains the horizontality of the fingers is applied only to the remaining fingers, excluding the thumb and middle finger, as shown in FIGS. 4 to 6. The configuration of the finger rotation member (150) is the same for all.

[0084] As shown in the drawing (see FIGS. 4 to 6), a finger placed on the finger support member (113) of the finger support member (110) and fixedly supported by a fixing band (115) has its nail outline photographed by a nail measuring device (camera) (see FIG. 3) before nail art treatment. This nail outline photographing is to check whether the nail is accurately leveled. However, since the shape of the nails of many users is different, and the fingers are a part that can move delicately due to many joints, the photographed appearance may vary greatly depending on how and from which direction the photograph is taken. Therefore, if nail printing is performed on the nail area extracted by photographing in this way, it may be difficult to achieve perfect printing because the print may go beyond the boundary of the nail.

[0085] Accordingly, the twisted angle of the nail is analyzed based on the image of the fingernail captured by the nail measuring device (10), and it is determined whether the image of the finger captured by the nail measuring device (10) is within the set range of the finger horizontal maintenance confirmation program preset in the nail measuring device (10). If it is determined that the captured horizontality is outside the preset horizontal maintenance range, the positive / negative rotation motor (M2) of the corresponding finger of the finger rotating unit (150) is driven in the positive or negative direction to rotate the finger support member (113) left and right on the upper surface of the base (114) according to the preset nail horizontal angle measurement signal of the nail measuring device (10) (see FIG. 3), thereby adjusting the nail horizontal angle of the corresponding finger to fall within the nail horizontal angle range preset in the camera (10) (see FIG. 3). When it is confirmed that the horizontal angle of the nail is within the range of the preset horizontal angle, the printer (30) can print (apply) accurate nail art on the surface of the user's nail.

[0086] Although the above embodiment has been described step by step to help understanding, nail art users will be able to fully understand from the configuration of the above embodiment that the nail art actually operates continuously the moment the finger is provided for nail art.
