Description

Technical Field

[0001] The invention relates to an eyelash curler. Prior art

[0002] Generally, an eyelash curler (eyelash curler, eyelash curler) is a structure using the principle of a lever, and is formed of metal such as stainless steel using two fingers.

[0003] However, in a general metal eyelash curler using the lever principle, a metal rod is twisted and formed into a ring shape in the gripping part, and two metal rods are extended side by side in other parts, so the metal cross section in the gripping part is thin and the holding property is poor. In addition, people with metal allergies cannot use it.

[0004] Therefore, in order to prevent metal allergies or make the skin feel soft, there have been proposed eyelash curlers in which corresponding parts such as the gripping part that contacts the fingers or the abutting surface that contacts the eyelids are partially covered with resin from above the metal, or a part of the component is partially composed of resin (for example, Patent Document 1, Patent Document 2).

[0005] In addition, as an eyelash curler in which the entire outer side is made of resin without using metal on the outer side, there is an eyelash curler having a spring (for example, Patent Document 3).

[0010] Patent Document 3: Japanese Patent Application Publication No. 2004-57581 Summary of the invention

[0011] Problems to be solved by the invention

[0012] However, if a resin portion is attached to a portion of a metal eyelash curler or a portion of the metal eyelash curler is replaced with resin as in Patent Documents 1 or 2, the number of manufacturing steps for assembly increases compared to a metal eyelash curler alone, and productivity decreases accordingly.

[0013] Furthermore, if a resin eyelash curler is formed in the same shape as a general metal eyelash curler, the strength for clamping is insufficient, so the entire outer side of the eyelash curler shown in Patent Document 3 is made of resin and a spring for clamping is provided. However, the provision of the spring makes the structure complex and large. In addition, in this structure, the appearance is different from that of a general metal eyelash curler using a lever and the operation method is different.

[0014] Therefore, in view of the above circumstances, an object of the present invention is to provide a resin eyelash curler which is not larger than a general metal eyelash curler in shape and has a sufficient strength and can be operated in the same manner as a metal eyelash curler.

[0015] Means used to solve problems

[0016] In order to solve the above problems, one embodiment of the present invention is:

[0017] Provided is an eyelash curler having:

[0018] a fixing member integrally formed with an upper pressing portion;

[0019] An acting member, wherein a lower pressure portion thereof is movable up and down relative to the upper pressure portion; and

[0020] A force point member that moves the action member up and down by rotating with the portion engaged with the fixing member as a fulcrum;

[0021] The fixing member, the acting member, and the force point member are each integrally formed of resin.

[0022] Effects of the Invention

[0023] According to one embodiment, a resin eyelash curler does not increase in size compared to a general metal eyelash curler, and can be operated in the same manner as a metal eyelash curler while ensuring strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Hereinafter, specific embodiments will be described with reference to the drawings. In the following, the same components are denoted by the same reference numerals in the drawings and duplicate descriptions are omitted.

[0045] The invention relates to a resin eyelash curler (an eyelash curler for global eyelashes and an eyelash curler for local eyelashes).

[0046] <First embodiment>

[0047] Figure 1This is an overall perspective view of an eyelash curler according to a first embodiment of the present invention. Figure 2 For from Figure 1 The whole perspective view of the eyelash curler of the first embodiment viewed from different directions. Figure 3 for Figure 1 Exploded view of an eyelash curler.

[0048] The eyelash curler 1 of the present embodiment has a structure similar to that of a general metal eyelash curler, and each member is integrally formed with the following resin.

[0049] The eyelash curler 1 includes a fixing member 10 , a force point member 20 , and an action member 30 .

[0050] The fixing member (also referred to as a support portion) 10 includes an upper side pressurizing portion 11, parallel struts 12A and 12B, inclined struts 13A and 13B, an arm 14, and a grip portion 16. The arm 14, which is a handle, is formed with a support hole 15. The arm 14 is also present above the support hole 15, and above the support hole 15 is a confluence portion 141J that merges with the inclined struts 13A and 13B.

[0051] The upper side pressing portion (also referred to as abutting member, upper clip, or frame) 11 is a portion that comes into contact with the upper surface of the upper eyelashes when the upper eyelashes are curled.

[0052] The parallel struts 12A and 12B are integrally connected from both ends in the width direction of the upper pressurizing portion 11, and extend in the vertical direction. The upper ends of the inclined struts 13A and 13B are connected to the lower ends of the parallel struts 12A and 12B, and the intervals at the lower sides are narrowed in a V-shape, and the lower ends are connected to the arm 14. The parallel struts 12A and 12B and the inclined struts 13A and 13B function as support parts.

[0053] The arm (also referred to as the first arm portion, handle portion, or shaft portion) 14 is an extension portion that connects the inclined support posts 13A and 13B to the handle portion 16. In this example, the arm 14 is a portion that is connected to the inner side of the handle portion 16, that is, a straight portion 161 (see Figure 3 ) extend in the same direction.

[0054] The hand-held portion (handle, finger ring, handle, grip) 16 is in the shape of a ring with finger holes formed therein. When the user curls the upper eyelashes by himself, the user's thumb is often inserted into the finger hole of the hand-held portion 16. Alternatively, when a makeup artist such as a makeup stylist curls the upper eyelashes or when the user curls the lower eyelashes by himself, the makeup artist's index finger, middle finger or ring finger is often inserted into the finger hole of the hand-held portion 16.

[0055] In the present invention, the fixing member 10 is integrally formed with a grip portion 16, an arm 14 extending in the up-down direction, a pair of support portions 12A, 13A, 12B, 13B branching from the arm 14 and supporting both ends of the upper pressurizing portion 11, and the upper pressurizing portion 11.

[0056] In addition, refer to Figure 3 Small holes 151A and 151B that penetrate in the width direction are formed on the side surfaces (side walls) of the support hole portion 15 formed in the arm 14. In this configuration, the side surfaces of the support hole portion 15 are defined to be wider than other portions of the arm 14, but may be the same width as other arms 14.

[0057] The power point member 20 has arm portions 21 and 24 and a grip portion 25. The front end side arm 21 is formed with a front end hole (front end engagement hole) 22 as a first engagement hole and a fulcrum hole (fulcrum engagement hole) 23 as a second engagement hole.

[0058] The arm portion (also referred to as the second arm portion, the handle portion, or the shaft portion) 21, 24 includes: a front end side arm 21 extending from the front end portion beyond the connecting portion; and a central arm 24 extending in a direction different from that of the front end side arm 21 and extending in a direction opposite to that of the inner side portion of the handle portion 25, that is, a straight portion 251 (see Figure 3 ) extend in the same direction.

[0059] The front end side arm 21 of the force point member 20 is inserted into the support hole portion 15 of the fixed member 10 from the end portion of the front end side opposite to the hand-holding portion 25, and is locked by the pin shaft PS2 in a manner that the fulcrum hole 23 and the small holes 151A, 151B on the side of the support hole portion 15 are aligned with each other while penetrating the fulcrum hole 23 and the small holes 151A, 151B.

[0060] By this engagement, the force point member 20 can rotate with the pin shaft PS2 as the rotation axis relative to the fixed member 10. That is, the force point member 20 uses the principle of the first lever, with the handle 25 as the force point, the engagement portion with the fixed member 10 as the fulcrum, and the upper end as the action point.

[0061] When the force point member 20 is rotated relative to the fixed member 10, Figure 3 The arm 14 of the fixing member 10 and the arm portions 21 and 24 of the force point member 20 shown are the stress generation range. The stress generation range includes the maximum stress generation portion where the stress becomes the maximum during use. Furthermore, the so-called stress generation range refers to the portion where relatively large stress is generated, and stress is also generated in other portions.

[0062] The hand-held portion (handle, finger ring, handle, grip) 25 is ring-shaped to form a finger hole for fingers to enter. For example, when a user curls the upper eyelashes by themselves, the user's index finger, middle finger or ring finger is often inserted into the finger hole of the hand-held portion 25. Alternatively, when a makeup artist curls the eyelashes or when curling the lower eyelashes by oneself, the makeup artist's thumb is often inserted into the hand-held portion 25.

[0063] The force point member 20 is integrally formed with a grip portion 25 and extended arms 21 and 24 . In the force point member 20 , the arms 21 and 24 are formed from one piece and have the same thickness as the grip portion 25 .

[0064] As described above, the front end side arm 21 is provided with the fulcrum hole 23 as a fulcrum and the front end hole 22 as a point of action, and the central arm 24 extends obliquely relative to the front end side arm 21. In addition, the central arm 24 is formed at the inner part of the handle part 25, that is, the straight part 251 (see Figure 3 ) By inclining the arm portions 21 and 24 of the force point member 20, the straight portion 251 of the grip portion 25 extending continuously from the arm 24 is substantially parallel to the straight portion 161 of the grip portion 16 extending continuously from the arm 14, so that force can be applied without being wasted.

[0065] In addition, refer to Figure 1 , Figure 2 , Figure 3 In the fixing member 10, the grip portion 16 is configured to form a finger hole by a straight portion 161 and a curved portion 162, and the straight portion 161 and the curved portion 162 are formed from the lower end of one arm 14 in the thickness direction y (refer to Figure 6C ) is branched at the branch point BP1, and the straight portion 161 extends linearly from the arm 14, and the curved portion 162 protrudes from the lower end of the straight portion 161 in the first thickness direction and folds back and returns to the branch point BP.

[0066] In addition, in the force point member 20, the hand-holding portion 25 is constructed to form a finger hole by a straight portion 251 and a curved portion 252, and the straight portion 251 and the curved portion 252 are branched from the lower end of the central arm 24 of the arm portions 21, 24 composed of one root at a branch point BP2 in the thickness direction, and the straight portion 251 extends linearly from the central arm 24 which is a part of the arm portion, and the curved portion 252 protrudes from the lower end of the straight portion 251 in the second thickness direction which is opposite to the first thickness direction and folds back and returns to the branch point BP2.

[0067] In the present embodiment, the finger holes formed in the grip portions 16 and 25 are teardrop-shaped.

[0068] The acting member (interlocking portion, lifting portion) 30 includes a lower side pressing portion 31 , link portions 32A and 32B, and a connecting portion 33 .

[0069] When curling your upper eyelashes, Figure 1 In the state shown, the eyelash curler 1 is grasped, and the lower pressing part (lower abutting member, clamping piece) 31 pushes up the lower surface of the eyelashes clamped between the upper pressing part 11 from the lower side, so that the upper eyelashes are curled upward.

[0070] In addition, when curling the lower eyelashes, Figure 1 The eyelash curler 1 is held upside down, and the lower pressing portion 31 pushes down the upper surface of the eyelashes clamped between the lower pressing portion 31 and the upper pressing portion 11 from the upper side to curl the lower eyelashes downward.

[0071] The link parts (lifting columns) 32A and 32B are connected to the lower pressurizing part 31 at their upper ends, are inclined in a substantially V-shape, and are connected to the connecting part 33 at their lower ends.

[0072] In this embodiment, a merging portion 332J where the link portions 32A and 32B merge before the engagement groove is provided on the upper end side of the connecting portion 33. The merging portion 332J reinforces the thinnest link portions 32A and 32B in the eyelash curler 1.

[0073] The connection part 33 has a U-shaped engagement groove at the three-dimensional front end. In addition, small holes 331A and 331B penetrating in the width direction are formed on the side surfaces forming both sides of the connection part 33.

[0074] The front end of the front end side arm 21 of the force point member 20 is inserted into the inner side of the U-shape of the connecting portion 33 of the action member 30, and is locked by the pin shaft PS1 in a manner that the front end hole 22 and the small holes 331A, 331B on the side of the connecting portion 33 are aligned.

[0075] By this engagement, when the power point member 20 rotates about the pin PS1 as the rotation axis, the action member 30 can be moved up and down in conjunction with it.

[0076] In addition, partially missing substantially circular (hook-shaped) engaging hooks (engaging portion, hooks at both ends) 311A ​​and 311B are provided at both ends of the lower pressure portion 31. The engaging hooks 311A ​​and 311B are engaged with a pair of parallel pillars 12A and 12B, so that the lower pressure portion 31 can slide along the parallel pillars 12A and 12B of the fixing member 10.

[0077] exist Figure 3 , an example is shown in which the engaging hooks 311A ​​and 311B are opened to the side (depth direction), but in the present embodiment, the engaging hooks 311A ​​and 311B may be opened to the rear (second thickness direction) when viewed from the front.

[0078] Furthermore, a clamp rubber CR (see FIG. 1 ) as an elastic member is inserted into the upper surface of the lower pressurizing portion 31. Figure 2 ). Therefore, a groove portion 312G for inserting the clamp rubber CR is formed on the upper surface of the lower side pressurizing portion 31.

[0079] Through this structure, if the handle 25 on one end side is moved in a manner close to the handle 16, the force point member 20 rotates with the connection part with the fulcrum hole 23 and the small holes 151A and 151B, that is, the pin shaft PS2 as the fulcrum (fulcrum B), thereby, the front end hole 22 connected to the connection part 33 of the action member 30 on the other end side moves in the direction opposite to the movement of the handle 25, and the action member 30 is pushed up together with the pin shaft PS1.

[0080] Thus, by moving the grip 25 , the action member 30 moves up and down according to the elevation of the distal end hole 22 , and the engaging hooks 311A ​​and 311B slide along the parallel struts 12A and 12B of the fixing member 10 , thereby moving the lower pressurizing portion 31 up and down.

[0081] Furthermore, the force point member 20 rotates with a part of the fixing member 10 as a fulcrum, thereby moving the action member 30 up and down.

[0082] The lower pressing portion 31 of the action member 30 approaches the upper pressing portion 11 of the fixing member 10 and applies pressure (curls) to the eyelashes between the clamp rubber CR and the upper pressing portion 11, thereby curling the eyelashes.

[0083] Figure 4A 2 is a front view of an eyelash curler 1 according to a first embodiment. Figure 4B It is a rear view of the eyelash curler 1 of the first embodiment.

[0084] Reference Figure 4A and Figure 4B , when the direction orthogonal to the direction of rotation of the power point member 20 is set as the depth direction, in the fixed member 10, at least a portion of the arm (first arm portion) 14 is equal to the width (x1) of the first grip portion 16 in the depth direction. In addition, in the power point member 20, the central arm 24, which is at least a portion of the second arm portions 21, 24, is equal to the width (x1) of the second grip portion 25 in the depth direction.

[0085] Reference Figure 1 to Figure 4B The straight portion 161 and the curved portion 162 of the first grip portion 16 overlap with the straight portion 251 and the curved portion 252 of the second grip portion 25 in the depth direction.

[0086] Here, "equal widths" and "overlapping" include not only completely equal or completely overlapping, but also partially overlapping with a certain degree of error. For example, the straight portion 251, 161 and the curved portion 252, 162 may have different widths, and in this case, the thicker portion may partially overlap the thinner portion in the depth direction.

[0087] In addition, refer to Figure 1 to Figure 4B In the present embodiment, the arm 14 is a single piece extending from the branch point to the handle 16 , and the width (depth) and height (thickness) of the handle 16 are the same as the width and thickness of the arm 14 in the depth direction.

[0088] With this configuration, the force of pinching the eyelashes is easily transmitted because the fingers directly apply the force of pinching the eyelashes during operation via the arms 14, 21, 24 extending in the same direction with the same width from the grips 16, 25 overlapped in the depth direction with the same thickness.

[0089] In the eyelash curler 1, the fixing member 10, the power point member 20, and the action member 30 are integrally formed of resin. The details of the constituent resin will be described below.

[0090] In addition, in this embodiment, the connection portion between the force point member 20 and the action member 30, and the connection portion between the fixed member 10 and the force point member 20 can be rotatably fixed by a connecting shaft, i.e., a pin shaft (PS1, PS2) used to connect the components, and the raw material constituting the pin shaft PS1, PS1 can be any raw material such as resin or metal.

[0091] Furthermore, if the pins PS1 and PS2 are formed of resin, all components constituting the eyelash curler 1 can be made of resin, and a completely metal-free structure can be achieved.

[0092] <Comparative Example>

[0093] Figure 5A , Figure 5B This is a diagram of a metal eyelash curler of a comparative example. Figure 5A , Figure 5B The eyelash curler 9 shown is an example of a general metal eyelash curler. Figure 5A 1 is a front perspective view of a metal eyelash curler 9 according to a comparative example. Figure 5B It is a rear perspective view of a metal eyelash curler 9 according to a comparative example.

[0094] About the metal eyelash curler 9, the following description and Figure 1 The eyelash curler 1 of the present invention has different structural features.

[0095] exist Figure 5A , Figure 5BIn the metal eyelash curler 9 shown, the fixing member 70 is formed by separately forming the upper side pressing part (metal frame) 71 and the thinner metal rod, and then connecting them. The force point member 80 is formed by deforming a thinner metal rod. The action member 90 is formed by separately forming the lower side pressing part (metal frame) 91 and the thinner metal rod, and then connecting them.

[0096] In detail, in the fixing member 70, a metal rod is processed and twisted into a ring shape at the lower end to form a handle 76, and a longitudinal cutout hole is pre-formed in the opposite parts of the two ends of the metal rod corresponding to the upper side of the parallel pillars 72A and 72B. In the arm 74 as an extension from the pillars 72A, 73A, 72B, 73B to the front of the handle 76, two thinner metal rods (741, 742) are arranged in a contact or close state. In addition, the upper side pressure part 71 is connected to the parallel pillars 72A and 72B by inserting a metal frame into the cutout hole on the inner side surface of the front end of the parallel pillars 72A and 72B as metal rods and welding them.

[0097] In the force point member 80, the lower end is twisted into a ring shape to form a handle portion 85, and in the arm portions 81 and 84 that serve as extensions from the handle portion 85 to the front end, two thinner metal rods (811, 812) and (841, 842) are arranged in a contacting state.

[0098] In the action member 90 , the end of a metal rod formed into a substantially V-shape by bending one metal is welded to the lower pressurizing portion 91 as a metal frame, and the link portions 92A and 92B are connected to the lower pressurizing portion 91 .

[0099] In addition, in the action member 90, when the apex of the substantially V-shaped link parts 92A and 92B is connected to the force point member 80, a relatively thin metal rod is inserted into the front end engaging hole 82 of the force point member 80 and bent to form the shape of the link parts 92A and 92B, and in this state, the upper ends of the link parts 92A and 92B are welded to the lower side pressurizing part 91. In this way, the molding of the action member 90 and the connection of the action member 90 and the force point member 80 are simultaneously performed, so that after manufacturing, the action member 90 and the force point member 80 will not be separated.

[0100] In this structure, the handles 76 and 85 that form a ring in the fixing member 70 and the force point member 80 have a thickness equivalent to that of a single arm relative to the arms 74 and (81 and 84) that are combined into two arms. Therefore, in the handles 76 and 85, the cross-section of the cylinder is thinner and the retention is poorer.

[0101] On the other hand, the eyelash curler 1 of the present invention is made of resin, and therefore, in the fixing member 10 and the power point member 20 , the arm 14 ( 21 , 24 ) is composed of one piece and has the same thickness as the grips 16 , 25 .

[0102] Thus, in the structure of the present invention, by making the cross-sectional shape of the gripping parts 16 and 25 in the fixing member 10 and the force point member 20 the same thickness as the arm parts 14, 21, and 24, the gripping parts 16 and 25 can be thickened, and the retention is improved, and even if force is applied, the fingers will not be embedded and there will be no pain, so that the force can be applied sufficiently.

[0103] Furthermore, in the eyelash curler 1 of the present invention, referring to Figure 3 , Figure 4A , Figure 4B The straight portion 161 and the curved portion 162 of the first grip portion 16 overlap with the straight portion 251 and the curved portion 252 of the second grip portion 25 in the depth direction.

[0104] Therefore, with Figure 5A , Figure 5B Compared with a grip part having a twisted straight portion and a curved portion as shown in the metal structure, a grip part overlapping in the depth direction directly applies force, so it is easier to operate and easier to apply force to the eyelashes.

[0105] In the metal eyelash curler 9, the arm 74 of the fixing member 70 is composed of two metal rods 741 and 742, and the interval between the rods is used as a sandwiching portion 75 adjacent to the lower part where the inclined pillars 73A and 73B are expanded, and the arm 81 of the power point member 80 is sandwiched from the side and the pin 83 is inserted, thereby engaging the arm 81 with the sandwiching portion 75. Therefore, the upper side of the part where the fulcrum of the arm 81 is sandwiched by the sandwiching portion 75 is exposed. When the eyelash curling action is performed using this structure, if the power point member 80 is rotated relative to the fixing member 70, there is a concern that hair, tissue, cosmetic cotton, etc. will be caught in the part where the fulcrum of the arm 81 is sandwiched by the sandwiching portion 75.

[0106] In contrast, in the present invention, the upper end of the arm 21 on the upper side of the support hole 15 through which the force point member 20 is inserted in the fixing member 10 has a confluence portion 141J, so the upper side of the fulcrum of the force point member 20 rotating relative to the fixing member 10 is not exposed. Therefore, even if hair or the like is present nearby, the possibility of being caught in the engagement portion between the force point member 20 and the fixing member 10 is low.

[0107] <Similar structure>

[0108] Since the eyelash curler has a complex shape, it is replaced with a simple shape and the shape calculation is performed.

[0109] Fig. 6A , Figure 6B , Figure 6C A diagram approximately illustrating how force is applied in an eyelash curler. Fig. 6A is a diagram showing the positions of the fulcrum and the load point in the eyelash curler. Figure 6B For the general Fig. 6A The support and load points are similar to those of a cantilever simply supported beam (single-sided concentrated load). Figure 6C It is a cross-sectional view of the beam portion of the fixed component and the force point component, which is equivalent to Fig. 6A D section.

[0110] It can be considered that at the moment of clamping the eyelashes, the rotation part of the eyelash curler, that is, the power point member 20, is restricted from rotating and hardly rotates or moves. Fig. 6A The connecting part of the eyelash curler shown can be replaced by Figure 6B The fulcrums A and B.

[0111] The load point C is set to the grip portion 25 of the power point member 20, and the load P is set to the force (gripping force) applied from the fingers to the eyelash curler.

[0112] Here, the fixed member 10 and the force point member 20 function as a "beam" of a cantilever simply supported beam. When considering the load or action, as shown in FIG. Figure 6C As shown, the width (depth) (x) and height (thickness) (y) of the cross section of the beam including the force-bearing portion, namely the fixing member 10 and the force point member 20 are considered.

[0113] In addition, in the description, Fig. 6A As shown in FIG. 1 , the direction in which the force point member 20 rotates is set as the rotation direction, and the direction orthogonal to the rotation direction is set as the depth direction. Figure 6C As shown in FIG. 1 , a direction perpendicular to the depth direction in the cross section of the fixing member 10 and the force point member 20 is defined as a thickness direction.

[0114] like Figure 6C As shown, the cross-sections of the arm 14 and the handle 16 of the fixing member 10 for directly applying force, and the arm 21, 24 and the handle 25 of the force point member 20 are preferably quadrilateral or rounded quadrilateral in order to increase the cross-sectional area without changing the thickness of the circular metal to obtain a stronger strength. However, Figure 6C The structure of the beam having a quadrilateral cross section shown in the figure is an example, and the cross-sectional shape of the beam of the fixing member 10 and the force point member 20 is not limited to Figure 6C The rectangular shape shown in the figure emphasizes moldability and touch, and other shapes such as a circle, an ellipse, or a semicircle may be used.

[0115] In addition, Figure 6B In the structure of the "cantilever simply supported beam (one-sided concentrated load)" shown, the bending moment MB generated around the support point B becomes maximum.

[0116] Therefore, the present inventors evaluated the situation of applying external force (load P) to an eyelash curler as an object through simulation based on a conventional metal eyelash curler, and selected a resin. The results are shown below. Fig. 8A.

[0117] Fig. 7A , Figure 7B It is a diagram showing the ratio of the dimensions in the force point component. Fig. 7A 1 is a diagram showing a configuration example of the eyelash curler 1 of the present invention taking into account the ratio of the force in the force point member and the movable angle. Figure 7B This is a diagram showing a configuration example of an eyelash curler taking into account the ratio of forces in a force point member.

[0118] When the above-mentioned cantilever simply supported beam (one-side concentrated load) structure is applied to an eyelash curler, the following aspects are generally known regarding the force point member.

[0119] The eyelash curler 1 is based on the principle of the first lever, and the force point member 20 is rotated, and the handle 25 is used as the force point to act on the action member 30, thereby performing a curling action. Therefore, the distance between the force point and the action point is farther than the distance between the fulcrum and the action point, and the eyelash curling action can be achieved with a lighter force. Therefore, it is well known that Fig. 7A , Figure 7B The distance a shown is designed to be less than the distance b.

[0120] In addition, regarding the dimensions of the distance a from the fulcrum B to the front end side and the distance b from the fulcrum B to the grip side in the power point member 20, considering the influence on the curling pressure (pressure to clamp the eyelashes) according to the principle of the lever, it is suitable to be a:b=1:3 or more. That is, in the power point member 20, the distance from the fulcrum to the lower end of the power point member 20 is set to be more than 3 times the distance from the upper end to the fulcrum. In this embodiment, in the power point member 20, the distance from the fulcrum hole 23, which is the fulcrum engaged with the fixing member 10 through the pin PS2, to the lower end of the power point member 20 is set to be more than 3 times the distance from the front end hole 22 engaged with the action member 30 through the pin PS1 to the fulcrum hole 23.

[0121] However, if portability is considered, a small size is more desirable. If only the ratio is set, for example, Figure 7B If the force point member 20 is a shorter structure, the force point and the point of application are close to the fulcrum B, and therefore, a considerable force must be applied to the handheld portion, and the movable angle at the fulcrum B must be set to be larger.

[0122] Therefore, in this embodiment, the straight portion 251 (see Fig. 6A) When the use feeling when pushing from the finger hole side and the value of the balance produced by the curling pressure alone are ensured to ensure that the movement amount of the lower side pressurizing part 31 is 4 mm or more, it is suitable to be a=10 mm or more in consideration of the movable angle or the force application method. That is, in the first embodiment, it is suitable to set the distance from the upper end to the fulcrum B in the force point member 20, that is, the distance from the front end hole 22 as the upper end to the fulcrum hole 23 located at the fulcrum B to 10 mm or more.

[0123] <Selection of raw materials>

[0124] Fig. 8A This is the evaluation result of eyelash curlers made of various materials and used. Figure 8B This is a graph showing the feasible range based on Young's modulus and section modulus.

[0125] In detail, Fig. 8A The purpose is to form a material having a specific cross-sectional area and cross-sectional modulus, such as SUS304 (stainless steel), nylon 6 / 10, polyamide (PA), fiber-reinforced resin obtained by adding 55% glass fiber (GF) to PA, polyetheretherketone (PEEK), polybutylene terephthalate (PBT), GF polyamide MXD6, and CF polyamide MXD6. Fig. 7A Evaluation results of using an eyelash curler of the size of .

[0126] In addition, regarding "PA+GF55%" as a fiber-reinforced resin, the strength evaluation was performed by changing the cross-sectional area and the cross-sectional modulus. By increasing the cross-sectional area, the cross-sectional modulus increases. Figure 8B The position on the graph moves upward, and there are cases where the evaluation is good even for the same raw materials. For example, in the case of a raw material of "PA+GF55%" and a cross-sectional modulus of 4.5 (mm 3 ) is not satisfactory in strength and is comprehensively judged as "×". 3 ) and the section modulus is 36(mm 3 ), the strength is satisfied and the comprehensive judgment becomes "0".

[0127] In addition, for PBT, even if the cross-sectional area is increased in the same manner as "PA+GF55%" (even if the cross-sectional modulus is set to 32 (mm 3 )), and the strength evaluation is not satisfied, so the comprehensive judgment is not "0".

[0128] exist Figure 8B The area surrounded by the four sides is the recommended range set by simulation. The recommended range is 2500 to 40000 (N / mm 2 ) of raw materials, and the cross-sectional coefficient is set to 5 to 40 (mm3 ).

[0129] In addition, within this range, the greater the Young's modulus of the resin, the smaller the cross-sectional modulus. That is, even if the Young's modulus of the resin is greater and the thickness is reduced in a manner closer to that of a metal product, strength can be ensured. Considering the operability of the user, the cross-sectional modulus is preferably 30 (mm 3 ) or less, and the cross-sectional modulus is preferably 20 (mm 3 )the following.

[0130] On the contrary, according to the simulation, even for a resin with a small Young's modulus and a relatively brittle structure, it is possible to achieve satisfactory strength by increasing the cross-sectional modulus. However, considering the workability, the upper limit of the cross-sectional modulus is set to 40 (mm2) so as not to increase the cross-sectional area excessively. 3 ).

[0131] Therefore, in order to improve the strength of the raw material containing resin without increasing the cross-sectional area, the raw material constituting the eyelash curler is preferably formed of a fiber-reinforced resin obtained by mixing glass fiber (GF) in the resin. For example, if glass fiber is added to a resin having the same cross-sectional modulus, the Young's modulus becomes larger, Figure 8B The position on the curve graph moves to the right.

[0132] In addition to or in place of glass fiber, CF (carbon fiber) may be mixed. For example, the fiber-reinforced resin is preferably blended with 30% by mass or more and 65% by mass or less of glass fiber (GF) or carbon fiber (CF).

[0133] By adding GF or CF, the rigidity of the resin material itself (such as PA) against deformation or fracture can be enhanced. For example, the general value of Young's modulus is PA: 1200~2900Mpa, etc., and by adding glass fiber, the Young's modulus can be increased (for example, set to 4725Mpa). In addition, by this addition, the following shape is obtained, that is, the tensile strength representing the resistance to deformation or fracture of the resin material itself (such as PA) can be controlled to about 30% in the structural analysis calculation. Therefore, the eyelash curler formed by the reinforced resin can approach the pressure of clamping the eyelashes of the metal eyelash curler.

[0134] The resin mixed with the glass fiber is not particularly limited as long as it is a resin that can be matched with the fiber. For example, examples of the resin include polyamide (PA) (including various nylons), polyetheretherketone (PEEK), polyethylene terephthalate (PET), ethylene glycol-modified PET (PETG), polyphenylene sulfide (PPS), polyamide MXD6, etc.

[0135] Here, polyamide MXD6 is a crystalline thermoplastic polymer obtained from meta-xylylenediamine (MXDA) and adipic acid. GF polyamide MXD6 used here is commercially available Reny (registered trademark) 1022H obtained by blending 50% of glass fiber (GF) in polyamide MXD6. CF polyamide MXD6 is commercially available Reny C408 obtained by blending 40% of carbon fiber (CF) in polyamide MXD6.

[0136] Furthermore, according to simulations, materials with relatively high strength in a single resin, such as a single special polyamide MXD6, have a strength of 5000 (N / mm2) even without being reinforced with glass fiber or carbon. 2 ) or more, the section modulus is 5 to 40 (mm 3 ) can be used as the raw material of the eyelash curler of the present invention.

[0137] In addition, even if it is not a special resin, as long as the Young's modulus of the resin is 2500 (N / mm 2 ) or more, even if it is nylon 6 / 10, PEEK, PET, PETG, PPS, etc., by setting the cross-sectional modulus to a larger value within the above recommended range, the eyelash curler can be formed as a single body without mixing glass fiber. In this case, it is estimated that the Young's modulus of these resin monomers other than nylon 6 / 10 is 2500 (N / mm 2 )~5000(N / mm 2 ), so if the section modulus is set slightly off the lower end of the above recommended range, for example, 10 (mm 3 ) or more, even if it is a resin monomer, a specific strength can be achieved and it can be used as the raw material of the eyelash curler of the present invention.

[0138] Here, the stress generation range of the fixing member 10 and the force point member 20 directly receiving the force of the user's finger, that is, the arm portions 14, 21, 24, preferably meets the above-mentioned recommended range of 2500N / mm 2 ~40000N / mm 2 Young's modulus and 5mm 3 ~40mm 3 The cross-sectional coefficient.

[0139] Furthermore, regarding the link parts 32A and 32B of the acting member 30 that is indirectly subjected to a force and performs a lifting action, if the material satisfies the Young's modulus in the above-mentioned recommended range, the section modulus of the predetermined thickness may be smaller than the recommended range.

[0140] <Local eyelash curler>

[0141] In the above embodiment, the description is made on the premise of a global type eyelash curler that clamps the entire eyelashes close to the entire width of the eye, but the eyelash curler having the above-mentioned material and cross-sectional shape of the present invention may also be a local eyelash curler.

[0142] Fig. 9 This is a diagram showing the structure of a partial eyelash curler according to a modified example of the first embodiment of the present invention.

[0143] Topical eyelash curler 2 Fig. 9 As shown in the figure, the structure is similar to the first embodiment, and the width of the upper pressing part 11P and the lower pressing part 31P for clamping the eyelashes is shorter in the depth direction. Therefore, the intervals between the support parts 12C, 13C, 12D, and 13D of the fixing member 10P and the intervals between the link parts 32C and 32D of the action member 30P are also narrower than those of the first embodiment.

[0144] The force required to curl the eyelashes locally by clamping them between the upper pressing part 11P and the lower pressing part 31P having a shorter width is smaller than the force required to curl the eyelashes with the entire width of the eye.

[0145] Therefore, if Fig. 9 As shown, the widths of the grip portion 16 and the grip portion 25 in a state where no force is applied are also set to be narrow so that the rotational movable range of the power point member 20P becomes smaller.

[0146] In this configuration, we also use Figure 8B The eyelash curler is formed of a resin within the recommended range of the Young's modulus and the section modulus shown in the figure. Thus, the eyelash curler can ensure strength, is not larger than a general metal shape, and can curl the eyelashes by the same operation as a metal one.

[0147] and then, Fig. 9 The local eyelash curler 2 shown requires less force than the global type, so if the raw material meets the Young's modulus in the recommended range, the section modulus of the specified thickness can also be smaller than the recommended range.

[0148] Furthermore, in the present configuration, in the fixing member 10P, there is a confluence portion 141J which merges with the inclined struts 13C and 13D at the upper end of the arm on the upper side of the engaging portion, so that even if there is hair, it can be prevented from being caught in the engaging portion between the force point member and the fixing member.

[0149] Furthermore, in this configuration, the straight portion and the curved portion of the gripping parts 16 and 25 overlap in the depth direction, so that force is directly applied, making it easier to operate and to apply force to the eyelashes.

[0150] <Second embodiment>

[0151] Fig.10It is an overall perspective view of an eyelash curler 3 according to a second embodiment of the present invention. Fig.11 For from Fig.10 The whole perspective view of the eyelash curler 3 of the second embodiment is seen from different angles. Fig.12 This is an exploded view of an eyelash curler 3 according to the second embodiment.

[0152] In this embodiment, the raw material and the like are the same as the resin used in the first embodiment, but the engagement (fulcrum) between the fixing member and the force point member and the engagement (action point) between the force point member and the action member are different in the hinge structure and the like.

[0153] like Fig.12 As shown, in this embodiment, a fitting groove 53 which is a groove (recess) for fitting formed by recessing the lower side of the hinge is formed in a portion of the power point member 50 slightly away from the front end.

[0154] like Fig.12 As shown, in the fixing member 40, a supporting hole portion 45 formed in the arm 44 is provided with a fulcrum shaft 48 for fitting that extends in the width direction (depth direction).

[0155] Moreover, when the front end side arm 51 of the force point member 50 is inserted into the supporting hole portion 45 of the fixing member 40 from the upper end side, the force point member 50 is pressed downward relative to the fixing member 40, and in the supporting hole portion 45, the engaging groove 53 engages with the fulcrum shaft 48, thereby connecting the force point member 50 to the fixing member 40.

[0156] The fulcrum shaft 48 of the fixing member 40 fitted into the fitting groove 53 of the power point member 50 becomes the second fulcrum ( Fig. 6A The force point member 50 is rotatably connected relative to the fixed member 40.

[0157] In addition, Fig.12 , an example is shown in which the fulcrum shaft 48 extends entirely in the width direction of the support hole portion 45 , but the fulcrum shaft 48 that can be fitted into the fitting groove 53 may also be in the shape of two-sided protrusions that protrude from the inner side surface of the support hole portion 45 and are interrupted in the center.

[0158] In addition, the arm 44 also exists above the support hole 45, and a confluence portion 441J that merges with the inclined pillars 43A and 43B exists above the support hole 15. Therefore, the fulcrum is not exposed, and even if hair, tissues, cosmetic cotton, etc. exist nearby, they can be prevented from being caught in the engagement portion between the power point member 50 and the fixing member 40.

[0159] The acting member 60 is provided with a lower pressurizing portion 61 and link portions 62A and 62B one end of which is connected to the lower pressurizing portion 61 .

[0160] In addition, at the left and right ends of the lower pressure part 61, there are provided a partially missing substantially circular (hook-shaped) engagement hook (engagement part) 611A, 611B. In this embodiment, in order to facilitate the attachment and detachment of the action member 60 relative to the fixed member 40 during assembly, the engagement hooks 611A, 611B are rearwardly open. The engagement hooks (rear hooks) 611A, 611B are engaged with a pair of parallel pillars 42A, 42B, and the action member 60 can slide and move along the parallel pillars 42A, 42B of the fixed member 40.

[0161] In this configuration, the other ends of the link parts 62A and 62B are bent into a U-shape and integrally formed, and the portion connecting the other ends of the link parts 62A and 62B at the other ends is a cylindrical fitting tube 63. The fitting tube 63 is an engaging portion of the action member 60.

[0162] A fitting hook 52 whose upper side is recessed is formed at the front end of the power point member 50 .

[0163] Then, the force point member 50 is pushed upward from the bottom relative to the action member 60, and the fitting hook 52 is engaged with the fitting tube 63, so that the force point member 50 is connected to the action member 60. In this way, the fitting hook 52 of the force point member 50 is fitted with the fitting tube 63 of the action member 60, and the action member 60 can move in conjunction with the action point of the force point member 50.

[0164] In this way, the connection between the fixing member 40 and the force point member 50 is realized by the hook shape ( Fig. 6A The second fulcrum B), and the connection between the force point member 50 and the action member 60 ( Fig. 6A The first fulcrum A) of the invention enables installation and removal without using a shaft through which the components are passed for connection.

[0165] Therefore, it is not necessary to use the metal pins PS1 and PS2 for connecting the members to each other in the first embodiment, and it is possible to achieve a completely metal-free engagement portion between the components.

[0166] In addition, the engagement state can be released by applying force in the direction of the hook falling off, so that the user can disassemble and assemble it by hand. For example, when the eyelash curler 3 is dirty, it can be disassembled and cleaned, thereby cleaning even small bumps and depressions of the engagement part, and then it can be assembled, so that even the fine parts can be kept clean.

[0167] In addition, when a cosmetic bag or luggage is suddenly loaded, damage can be avoided by the hook falling off. Fig. 6A) and the second fulcrum B, the engagement direction is in the opposite direction. Therefore, when a strong force is applied in one direction, only the engagement state of either the first fulcrum A or the second fulcrum B will be disengaged. Therefore, when the engagement state is accidentally disengaged, it can be easily restored.

[0168] In addition, at the front end of the front end side arm 51 of the force point member 50, an engaging hook 52 with a recessed upper side is provided, and at a portion of the front end side arm 51 closer to the front end than the hand holding portion 55, an engaging groove 53 with a recessed lower side is formed, and the arm portions (second arm portions) 51, 54 are extended from the front end to the hand holding portion 55 in one line.

[0169] Therefore, in the eyelash curler 3 of this embodiment, unlike the first embodiment, the grips 46 and 55 can be thickened to the same thickness as the extensions (arms 44, 51, 54), thereby improving the holding performance compared to metal.

[0170] Here, to meet Fig. 6A In the present embodiment, in the force point member 20, the distance from the engaging groove 53 which is a fulcrum for engaging with the fixing member 40 to the lower end of the force point member 50 is set to be more than three times the distance from the engaging hook 52 which is the upper end for engaging with the action member 60 to the engaging groove 53.

[0171] In this embodiment, the distance from the fitting hook 52 as the upper end to the fitting groove 53 as the fulcrum is set to 10 mm or more so as to ensure that the movement amount of the lower pressurizing portion 31 is 4 mm or more.

[0172] Reference Fig.12 In the center arm 54 of the power point member 50 , a portion closer to the grip portion 55 than the fitting groove 53 and a leading surface in the rotation direction are formed with projections and depressions in a corrugated shape.

[0173] The corrugated concavo-convex shapes 541 and 542 improve the fit. In particular, when applying makeup by oneself, the thumb is inserted into the finger hole of the grip part 46 on the side of the fixing member 40, and the other fingers are inserted into the finger holes of the grip part 55 on the side of the force point member 50. When the middle finger, which is the easiest to apply force, is inserted into the finger hole of the grip part 55 or the ring finger is inserted into the finger hole, the corrugated concavo-convex shapes 541 and 542 also support the force point member 50 with the index finger or the middle finger, and the action is stable.

[0174] Furthermore, a finger hook portion (also referred to as a finger rest or finger placement portion) 56 is provided at the rear end of the grip portion 55. For example, when the user curls the eyelashes by himself, the user inserts the middle finger into the finger hole of the grip portion 55 on the force point member 50 side and the ring finger into the finger hook portion 56, or inserts the index finger into the finger hole of the grip portion 55 on the force point member 50 side and the middle finger into the finger hook portion 56, or inserts the ring finger into the finger hole of the grip portion 55 on the force point member 50 side and the little finger into the finger hook portion 56.

[0175] In this way, no matter which finger is inserted, in addition to the finger inserted into the finger hole of the hand-holding part 55, the corrugated concave-convex shape 541, 542 and the finger hook part 56 are also used to support the force point component 50. Therefore, when curling the eyelashes, the burden on one finger during pushing is shared, and the action is stable.

[0176] Furthermore, hit points 47 and 57 are provided respectively at the portions facing each other when the grip portion 46 of the fixing member 40 and the grip portion 55 of the power point member 50 are closed.

[0177] When pressing the eyelashes, the front ends of the collision points 47 and 57 of the grips 46 and 55 abut against each other, thereby preventing the power point member 50 from being excessively rotated relative to the fixing member 40 .

[0178] Furthermore, since the collision points 47 and 57 are provided at the inner edge of the gripping parts 46 and 55, the rotation is restricted. Therefore, if the clamp rubber (not shown) is flattened and becomes thin due to repeated use, for example, there is a concern that the clamping pressure of the pressurizing part during pressing may become insufficient. Therefore, when the collision points 47 and 57 are provided, it is appropriate to set the length to include the case where the clamp rubber is flattened.

[0179] Fig.13A , Fig. 13B It is a front view and a rear view of the eyelash curler 3 of the second embodiment.

[0180] Reference Fig.13A and Fig. 13B , when the direction orthogonal to the direction of rotation of the power point member 50 is set as the depth direction, in the fixed member 40, at least a portion of the arm (first arm portion) 44 is equal to the width (x2) of the hand-held portion 46 in the depth direction. In addition, it can be seen that in the power point member 50, at least a portion of the second arm portions 51, 54 is equal to the width (x2) of the hand-held portion 55 in the depth direction.

[0181] In the present embodiment, since the corrugated concavo-convex shapes 541 and 542 and the collision points 47 and 57 are provided, the thickness (height) and width of the beams of the arms 44 , 51 and 54 or the grips 46 and 55 in the rotation direction are non-uniform.

[0182] However, in the present embodiment, the center line CL of the arms 44, 51, 54 in the depth direction (the direction of the width x2) also extends in the same direction as the center line CL of the grips 46, 55 and overlaps. Therefore, during operation, the force of pinching from the fingers is directly applied from the grips 46, 55 via the arms 44, 51, 54 extending on the same center line, so that the force of pinching the eyelashes is easily transmitted.

[0183] In addition, refer to Fig.10 , Fig.11 , Fig.12 In the fixed component 40, the hand-holding portion 46 is constructed to form a finger hole by a straight portion 461 and a curved portion 462, the straight portion 461 and the curved portion 462 branch from the lower end of an arm 44 at a branch point BP1 in the thickness direction, and the straight portion 461 extends straight from the arm 44, and the curved portion 462 protrudes from the lower end of the straight portion 461 in the first thickness direction and folds back and returns to the branch point BP1.

[0184] In addition, in the force point member 50, the hand-holding portion 55 is configured to form a finger hole by a straight portion 551 and a curved portion 552, and the straight portion 551 and the curved portion 552 branch from the lower end of an arm portion 51, 54 at a branch point in the thickness direction, and the straight portion 551 extends linearly from the central arm 54 which is a part of the arm portions 51, 54, and the curved portion 552 protrudes from the lower end of the straight portion 551 in a second thickness direction which is opposite to the above-mentioned first thickness direction and folds back and returns to the branch point.

[0185] In the present embodiment, the finger holes formed in the grip portions 46 and 55 have a substantially semicircular shape.

[0186] Reference Figure 10 to Figure 13B The straight portion 461 and the curved portion 462 of the grip portion 46 of the fixing member 40 overlap with the straight portion 551 and the curved portion 552 of the grip portion 55 of the power point member 50 in the depth direction.

[0187] Furthermore, in this configuration, the straight portion and the curved portion of the gripping parts 46 and 55 overlap in the depth direction, so that force is directly applied, making it easier to operate and to apply force to the eyelashes.

[0188] In this embodiment, the Figure 8B The resin within the applicable range defined by the cross-sectional modulus and Young's modulus shown above can achieve the same stress by bending and curling pressure as metal. Therefore, the gripping property of the grip can be improved, and the shape is not enlarged compared to metal, the strength can be ensured, and the eyelash curling effect equivalent to that of metal can be exerted by the same operation as metal.

[0189] In addition, in the second embodiment, in the structure in which the action point (fulcrum A) and the fulcrum (fulcrum B) are engaged with each other using hooks and grooves of the constituent elements, an example of setting corrugated convex and concave shapes 541, 542 and collision points 47, 57 is used, but the corrugated shape and collision points can also be applied to the first embodiment engaged by a pin shaft.

[0190] Alternatively, in the configuration of the second embodiment in which the components are engaged with each other using hooks and grooves, the corrugated concavo-convex shapes 541 and 542 and the collision points 47 and 57 may not be provided.

[0191] In the configuration in which the hooks and grooves of the components are engaged with each other as the action point and the fulcrum, the beams of the arms 14, 21, 24 and the handles 16, 25 may be configured to have the same thickness as well as the same width as in the first embodiment.

[0192] In the first embodiment, a grip portion having a substantially teardrop-shaped finger hole is described, and in the second embodiment, a grip portion having a substantially semicircular finger hole is described, but the shape of the finger hole may be opposite, or may be circular, elliptical, etc. Furthermore, the grip portion may be interrupted around the branch point of the curved portion.

[0193] As mentioned above, although the preferred embodiment of the present invention has been described in detail, the present invention is not limited to the above-mentioned specific embodiment, and various modifications and changes can be made within the scope of the gist of the embodiment of the present invention described in the claims.

[0194] This application claims priority based on Japanese Patent Application No. 2018-174220 filed with the Japan Patent Office on September 18, 2018, and all the contents of Japanese Patent Application No. 2018-174220 are hereby incorporated by reference into this application.

Claims

1. An eyelash curler comprising: a fixing member integrally formed with an upper pressing portion; an acting member, wherein a lower pressure portion is movable up and down relative to the upper pressure portion; and a force point member that moves the action member up and down by rotating with the portion engaged with the fixing member as a fulcrum, The fixing member, the acting member and the force point member are each integrally formed of resin. The fixing member is integrally formed with the upper pressure part, a first grip part on which the user's fingers rest, a first arm part extending in the up-down direction, and a pair of pillars branching from the first arm part and supporting both ends of the upper pressure part. The power point member is integrally formed with a second grip portion for the user's fingers to rest on and an extended second arm portion. The first arm portion is formed with a support hole portion through which the force point member is inserted. When the direction perpendicular to the rotation direction of the force point member is set as the depth direction, and the direction perpendicular to the depth direction in the cross section of the fixing member and the force point member is set as the thickness direction, In the fixing member, the first grip portion is in the shape of a ring formed by branching and folding a protrusion from the lower end of the first arm portion on one side in the thickness direction to form a finger hole. In the power point member, the second grip portion is a ring shape formed by branching and protruding from the lower end of the second arm portion on the other side in the thickness direction and folding back to form a finger hole, The portion of the first arm other than the supporting hole, the first grip, the portion of the second arm other than the end on the opposite side of the second grip, and the width of the second grip in the depth direction and the thickness in the thickness direction are equal. The first arm portion of the fixing member is composed of one piece, and the second arm portion of the power point member is composed of one piece.
