Description

Technical Field

[0001] The present invention relates to a pinching manual nail corrector capable of flattening and correcting deformed nails, and more particularly to a pinching manual nail corrector that can safely press and correct deformed nails into a substantially flat shape without crushing them under the control of pressure adjustment by the grip or pinch force of an operator.

Background Art

[0002] In the invention of conventional correctors for treating deformed nails, correctors for pinching and correcting a curved and deformed nail into a substantially flat shape have been proposed.

[0003] For example, Patent Document 1 invented by the applicant of the present application in the past first mounts a corrector formed in a substantially U-shaped cross-section on the flat part of the nail tip in a front view, and then laterally slides it to the nail edge part of the nail to be wound, and corrects the wound nail by a pinching correction method by lateral sliding insertion. Also, an ingrown nail corrector proposed in the invention of the applicant of the present application described in Patent Document 2 uses a holding tool separate from the corrector together with the corrector to pinch the ingrown nail into a substantially flat shape, and corrects the ingrown nail by fastening it to the nail while plastically deforming the corrector.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The correction method using the corrector having a clamping structure in the shape of a clip with a U-shaped cross section in the above-mentioned Document 1, and having a smooth gap which is an opening for inserting a claw and is thinner than the height of the claw thickness formed by the separated U-shaped cross section, is as follows: after inserting the substantially central flat portion in the front view of the claw tip of the curled claw into the smooth gap, it is slid to the edge end portion of the claw where the nail plate is curled inward in a curved shape into the nail bed and deformed, and the corrector having the clip-shaped clamping structure is clamped to the claw in a state where the curved claw edge portion is shaped into a flat shape by the clamping force of the corrector. However, in the case of this correction method, not only is the clamping correction performed with the inherent clamping force of the corrector without considering the embrittlement of the claw, but it also has a clamping adhesion strength that does not detach from the claw. As a result, in addition to claw splitting and loss of the edge end portion of the claw, splitting may occur and abrasion marks may also be seen on the surface of the nail plate, so it cannot be said to be an easily handled corrector.

[0006] Also, in the case of the ingrown nail corrector using the correction means by plastic working in the above-mentioned Document 2, it is a means of plastically deforming the ingrown nail corrector using a clamping tool separate from the ingrown nail corrector and clamping it to the deformed nail. However, since the clamping by the clamping tool can apply pressure to a thickness thinner than the thickness of the claw, there is a risk of crushing due to overpressure and the nail plate being crushed and bruised. Also, abrasion marks may be left on the surface of the nail plate. Thus, since it is difficult to control the clamping pressure for the conventional corrector using the clamping pressure, the handling of the ingrown nail corrector has not been easy.

[0007] An object of the present invention is to provide a clamping artificial nail corrector that can safely exhibit the effect of the clamping correction means without causing abrasions or abrasion marks such as crushing due to overpressure even for those inexperienced in the curling nail correction procedure using a clamping corrector.

Means for Solving the Problems

[0008] The clamping artificial nail corrector of the present invention for solving the above problems is composed of the following technical means.

[0009] The structure according to claim 1 of the present invention includes an upper claw pressing leg portion 1 provided with a downward claw contact surface portion 1A formed integrally or as a separate member, and a lower claw pressing leg portion 2 provided with an upward claw contact surface portion 2A formed integrally or as a separate member that is configured to overlap with the downward claw contact surface portion 1A. The upper claw pressing leg portion 1 and the lower claw pressing leg portion 2 are disposed opposite to each other in a spaced-apart state, and the upper claw pressing leg portion 1 and the lower claw pressing leg portion 2 are relatively moved closer to each other. A deformed claw inserted and disposed between the downward claw contact surface portion 1A and the upward claw contact surface portion 2A is pinched and pressed from above and below by the downward claw contact surface portion 1A and the upward claw contact surface portion 2A so that the claw can be flattened. The pinching manual claw corrector 10A is selected from a pliers type, a lever type, or other gripping and pinching structures. In the vicinity of the jaw tip portion where the downward claw contact surface portion 1A and the upward claw contact surface portion 2A overlap, when the upper claw pressing leg portion 1 and the lower claw pressing leg portion 2 are in the maximum pinching state or the closest state, the downward claw contact surface portion 1A and the upward claw contact surface portion 2A face each other with a relative minimum separation height that is greater than or equal to the claw thickness and has a depth greater than or equal to the length of the free edge of the claw tip so that the tip of the claw does not hit, and a separation gap portion 8 is provided. This is a pinching manual claw corrector characterized by this.

[0010] In the case of a pinching manual claw corrector in which it is difficult to form the separation gap portion 8, a separation gap holding body 9 having a function of restraining the pinching pressure may be installed on either one or both of the upper pressing leg portion 1 and the lower pressing leg portion 2 so as to satisfy the conditions for forming the separation gap portion 8.

[0011] When flattening the deformed claw by pinching in this way, the present invention relates to a pinching manual claw corrector characterized in that the separation gap portion 8 is formed to prevent crushing of the claw due to overpressure that presses the claw thickness, abrasions reaching inside the nail bed, or scratches on the nail surface.

[0012] In addition, the configuration described in claim 2 of the present invention is such that the downward claw contact surface portion 1A and the upward claw contact surface portion 2A of the upper claw pressing leg portion 1 and the lower claw pressing leg portion 2 in the maximum clamping state face each other, and the minimum opposing separation height of the separation gap portion 8 can be adjusted in terms of the separation height of the separation retainer 9 according to the progress of hypertrophic nail disease or nail deformation symptoms. The bolt screw insertion depth adjustment means that can change the protruding length as a function, or the ratchet tooth and plate serration protrusion adjustment means by rotation tooth stop nail control, etc., are separation height adjustment means that can freely change the convex protruding amount, or a structure that allows the protruding height of the convex separation gap adjustment type retainer 10 to be exchanged and changed in view of the nail thickness, or a splicing structure provided with an outer peripheral surface thread on the insertion portion of the protruding portion of the separation gap retainer 10 and an inner peripheral surface thread for receiving the insertion portion of the protruding portion for splicing. By equipping and interposing a separation gap adjustment type retainer 10 having a function selected from any of these, it is possible to respond to delicate nail thickness heights in view of the deformed state of the nail and individual differences, thereby enhancing safety and preventing crushing due to overpressure during clamping correction for various nail deformations. This relates to a clamping manual nail corrector characterized by this.

[0013] Note that the pliers type used in the present invention is composed of a first nail clamping half body 6 formed by providing the downward claw contact surface portion 1A on the tip side of the upper pressing leg portion 1 and a gripping operation portion 4 on the base end side of the upper pressing leg portion 1, and a second nail clamping half body 7 formed by providing the upward claw contact surface portion 2A on the tip side of the lower pressing leg portion 2 and a gripping operation portion 4 on the base end side of the lower pressing leg portion 2. The upper pressing leg portion 1 and the lower pressing leg portion 2 arranged opposite each other are relatively moved closer by the opening and closing operation of the gripping operation portion 4, and are configured to be able to sandwich and press-correct a deformed nail inserted between the downward claw contact surface portion 1A and the upward claw contact surface portion 2A. This relates to a clamping manual nail corrector.

[0014] The above-mentioned lever type used in the present invention is composed of two elastic long plates, which are arranged opposite to each other vertically and the rear ends thereof are joined to form a bifurcated shape, or is composed of one elastic long plate, which is arranged opposite to each other vertically and bent into a U shape from the approximate center in the longitudinal direction so that the legs separated vertically from the rear end to the front end form an upper pressing leg 1 and a lower pressing leg 2. A substantially cylindrical lever action support shaft 22 penetrating a lever action support shaft through hole 21 provided near the tip of each of the upper pressing leg 1 and the lower pressing leg 2, and a pressing operation handle 23 pivotally connected so as to be swingable around the diameter direction of the lever action support shaft 22 near the upper end of the lever action support shaft 22 are provided. A downward claw contact surface portion 1A formed by bending the tip of the upper pressing leg 1 downward and an upward claw contact surface portion 2A formed by bending the tip of the lower pressing leg 2 upward approach and separate by the swing of the pressing operation handle 23, and it relates to a clamping manual claw corrector configured to be able to sandwich and press-correct a deformed claw inserted between the downward claw contact surface portion 1A and the upward claw contact surface portion 2A.

[0015] In addition, the shape of the tip side of both legs of the lower claw pressing leg 2 that overlaps with the upper claw pressing leg 1 of the clamping manual claw corrector may be selected from any of a concave curved shape or a flat shape when viewed from above in a plan view and a convex curved shape or a flat shape when viewed from above in a front view from the tip side.

Advantages of the Invention

[0016] According to the invention according to claim 1 as described above, since the separation gap portion 8 capable of suppressing over-pressurization during gripping is provided on the chin tip side of the clamping manual claw corrector 10A, when flattening and clamping and correcting a curved deformed claw, even if over-pressurization during gripping that crushes the claw thickness is applied, the claw thickness can be maintained. Thus, even if an operator with little experience in claw correction treatment handles it, it is possible to prevent injuries such as abrasions caused by digging into the nail that induces crushed claws or cracked claws, and it is possible to safely and easily perform clamping correction of the deformed claw by gripping.

[0017] Further, according to the invention according to claim 2, by forming the separation gap adjustment type holder 10 capable of adjusting the opposing separation height of the separation gap portion 8, delicate adjustment corresponding to the separation height of the separation gap portion 8 in view of the deformed state of the nail and individual differences in nail quality becomes possible.

Mode for Carrying Out the Invention

[0019] Embodiments of the present invention will be briefly described with reference to the drawings showing the operation of the present invention. However, the present embodiment is not limited to the following. For example, within the range not impairing the gist of the present invention, a downward nail contact surface portion 1A is provided on the tip side of the upper nail pressing leg portion 1 and an upward nail contact surface portion 2A is provided on the tip side of the lower nail pressing leg portion 2. A separation gap retainer 9 that can brake the pinch with a separation of the minimum opposing separation height at the maximum pinch state greater than or equal to the nail thickness may be used. Also, as long as the function of the separation gap retainer 9 is not impaired other than in FIG. 1, its shape and means can be arbitrarily changed and implemented. Further, in a hand tool serving as a gripping and pinching means, as long as it is a pinching hand tool capable of forming the separation gap portion which is a feature of the present invention, it is not limited to a pliers type or a lever type, and can be arbitrarily selected from pinching hand tools such as a biting type or a pliers type and implemented.

Examples

[0020] Specific Example 1 of the present invention will be described with reference to the drawings. (See FIG. 1)

[0021] In FIG. 1 of this embodiment, an upper pressing leg portion 1 provided with a downward claw contact surface portion 1A on the tip side formed with a lateral width of 7 mm near the jaw portion, and a lower pressing leg portion 2 provided with an upward claw contact surface portion 2A on the tip side are such that when in the maximum clamping state, the relative minimum separation height at which the downward claw contact surface portion 1A and the upward claw contact surface portion 2A face each other is 0.5 mm, and a separation gap portion 8 having a separation depth of 10 mm from the tip edge is formed. In consideration of contact with claws that are easily scratched, the vicinity of the tip of the jaw or the claw contact surface portion may be integrally formed with the clamping semi-bodies 6 and 7 or formed using a separate member selected from metals, hard rubber, elastomers, resins, etc.

[0022] FIG. 1(a) of this embodiment is an enlarged perspective view showing a state where the upper pressing leg portion 1 and the lower pressing leg portion 2 are in an expanded and separated state. A separation gap holding body 9 for ensuring the relative minimum separation height is disposed between the upper pressing leg portion 1 and the lower pressing leg portion 2 in the previous stage. However, if the relative separation height is provided to be greater than or equal to the claw thickness in the shape of the clamping hand tool, it is not necessarily required to provide the separation gap holding body 9.

[0023] FIG. 1(b) of this embodiment shows that when in the maximum clamping state for clamping and correcting a deformed claw inserted and disposed between the downward claw contact surface portion 1A and the upward claw contact surface portion 2A, the minimum separation height at which the opposing surfaces of the separation gap portion 8 face each other is 0.5 mm, and the separation gap holding body 9 in the shape of a convex portion with a height of 0.25 mm is disposed on the opposing surfaces of the upper pressing leg portion 1 and the lower pressing leg portion 2 in the previous stage so as to be in overlapping contact at a depth of 10 mm from the tip edge of the corrector.

Embodiment

[0024] Also, in this embodiment, FIG. 3 is a perspective view of a pliers-type clamping hand claw corrector 30A, and FIG. 5 is a perspective view of a lever-type clamping hand claw corrector 40A. The figure shows a state in the case of a structure constituted by a bolt screwing depth adjusting type holding body using a separation adjusting bolt 12 into which a separation gap adjusting type holding body 10 provided in each is screwed in a manner that the common separation gap height can be adjusted.

[0025] According to the configuration shown in FIG. 3, by changing the screwing depth of the spacing adjustment bolt 12, the opening / closing degree of the spacing gap portion 8 can be adjusted to adapt to the individual differences in the claw thickness of the deformed claw. The bolt screwing depth adjustment type holder is structured using the spacing adjustment bolt 12 screwed in such a manner that the height of the spacing gap can be adjusted. Between the spacing adjustment bolt 12 screwed into the fixing nut 13 fixed to the spacing gap adjustment type holder through-hole 14 provided in the upper pressing leg portion and the first claw clamping semi-body 6, by externally providing a push spring to the bolt 12 so as to bias it in the direction in which the rotation of the bolt 12 is suppressed, a structure in which the height of the adjustment bolt can be held by the push spring is obtained, enabling the adjustment of the height of the spacing gap.

Example

[0026] Also, as shown in FIG. 7, it is a perspective view of a lever-type clamping manual claw corrector 40B, showing a state in the case of being composed of an adjustment plate-shaped serration type spacing gap height adjustment type holder structured such that the height of the spacing gap can be adjusted by the protruding height of a plate-shaped serration provided with ratchet teeth for the spacing gap adjustment type holder.

[0027] According to the configuration shown in FIG. 7, by changing the protruding height of the plate-shaped serration 31 provided with ratchet teeth, the opening / closing degree of the spacing gap portion 8 can be adjusted to adapt to the individual differences in the claw thickness of the deformed claw. It is a ratchet tooth serration plate protruding adjustment type holder by rotation tooth stop claw control, and by providing a plate-shaped serration that externally mounts ratchet teeth at a position meshing with a tooth stop claw pivotally mounted in a hole in the lower pressing leg portion so as to mesh and lock with the ratchet teeth, the adjustment of the height of the spacing gap is enabled. Note that each dimension may be appropriately changed according to the shape and thickness of the deformed claw 2.

[0028] The clamping manual claw correction tools 30A, 40A, and 40B are made of stainless steel. However, as long as they can be used safely in the claw clamping operation, for example, in addition to elastomers and hard rubbers, from metals, steel, aluminum, titanium, cobalt alloys, etc., and from resins, ABS, PE, PP, PS, PVC, FRP, ionomer, acrylic, PET, etc. can be selected and used. Also, on the claw contact surface of the upper and lower claw contact surfaces, in addition to polyethylene, polypropylene, urethane, ultra-high molecular weight polyethylene with high self-lubricity, and Teflon, which are resin-made cushioning materials, MC nylon, POM, PEEK, etc. may be arranged.
