Description

Technical Field

[0001] This invention relates to a pet nail trimmer, a tool for cutting pet nails, wherein the basic setting of the tool forms a circular blade, allowing the user to choose between placing the nail directly on the circular blade for cutting or opening the blade to insert and cut the nail from the front. The degree of opening can be adjusted according to cats and dogs to maximize ease of use. Background Technology

[0002] This section provides only background information relevant to the content of this application and is not necessarily prior art.

[0003] In existing pet nail trimmers, two parts are combined in a scissor shape, with a semi-circular blade at one end that makes one blade face each other and overlap in a way that does not distinguish between dogs and cats, so that it can be used like scissors.

[0004] Especially when trimming long, thin nails like a cat's, these pet nail trimmers are prone to making mistakes. If they cut too deep, they can hit nerves and potentially cause bleeding. To prevent this, existing technology aligns the circular blades (cutting blades) of each component, placing the nail on one blade for cutting. However, these blades are perforated into a circular shape and cannot open into a semi-circular form. Therefore, it's impossible to approach from the front of the blade, resulting in the problem that it can only be used when the animal's nail diameter is smaller than the diameter of the perforation. Furthermore, some users dislike aiming and inserting the nail before cutting.

[0005] Furthermore, dogs and cats have different nail sizes, and because of this difference, a single type of trimmer cannot be used. Therefore, if you own both a dog and a cat, it can be inconvenient to need to purchase two different trimmers.

[0006] In this invention, the cutting method that uses two semi-circular blades spread open to form a scissor shape is called open cut, and the cutting method that uses a perforated circular blade is called hole cut.

[0007] Korean Patent No. 10-1978625, US Patent No. US2017 / 0245469, and US Patent No. US2016 / 0066542 relate to tools with an open cutting method, while Korean Design Patent No. 30-1210834 relates to tools with a hole cutting method.

[0013] Patent Document 0004: Korean Design License No. 30-1210834 Summary of the Invention

[0014] This invention addresses the problems described above and overcomes the shortcomings of existing tools for cutting two types of pet nails. It allows for the use of only the advantages of tools that can be used to cut nails according to the needs of the object being cut or the user. In this way, nails can be directly inserted into a circular blade shape and cut in one tool (hole-type cutting method), or the blade can be opened to approach and cut from the front (open cutting method).

[0015] The pet nail trimmer of the present invention is characterized in that the cutting blades on the front side of the first body and the second body connected by a rotating shaft include large cutting blades and small cutting blades of different sizes, and one or more of the large cutting blades and the small cutting blades are formed into a semi-circle to form a circular hole or an open structure with the front side open. The cutting blades are adjusted to the position with the circular hole or the open position by the user selecting the position adjustment unit, and then the nail is inserted from the side or from the front to the back for use. When cutting with the small cutting blade, the first body and the second body are rotated only until the small cutting blade cuts the nail.

[0016] The invention is characterized in that a single-sized cutting blade is used by forming a circular hole through a position adjustment unit or by setting it into an open structure with the front side open.

[0017] The present invention is characterized in that the large cutting blade and the small cutting blade are arranged in a row or circumferential direction, and the position adjustment unit can be used to select whether the first body and the second body are rotated until the small cutting blade cuts the nail or until the large cutting blade cuts the nail.

[0018] The present invention is characterized in that the position adjustment unit is a combination of a position adjustment knob rotatably connected to the first body and a circular blade support formed on the second body, or a combination of a circular blade support formed on the second body and a rotation barrier wall formed on the first body.

[0019] According to the pet nail trimmer of the present invention, when the position control knob is set to the first level, all the cutting blades form circular holes. A slender cat's nail can be inserted into the small circular hole of the blade and the handle slightly tightened for cutting. When set to the second level, a slightly thicker dog's nail is inserted into the large circular hole and the handle is tightened more than in the first level. In this case, the second level can also be used to cut cat or dog nails regardless of the first level. When the position control knob is set to the third level, the blades of the first and second bodies can be opened into scissors, allowing the cat or dog's nail to be placed on the blades through the front opening for cutting. Cutting through the holes prevents the nail from being inserted too deeply, thus preventing excessive cutting and potential nerve damage or bleeding. Cutting with the blades open like scissors allows for quick and convenient cutting regardless of nail thickness, and also allows the user to choose between these two methods of use.

[0020] Because the present invention allows users to choose between two methods, hole-type cutting and open cutting, it has the unique effect of being used in accordance with the user's preferences and habits. Since it has both a small cutting blade for cat nails and a large cutting blade for dog nails, cat and dog nails can be trimmed by purchasing only a single tool. This also has the unique effect of reducing costs and making management easier compared to the previous situation of purchasing and using two tools. Attached Figure Description

[0032] The present invention will now be described. Detailed descriptions of known functions or structures will be omitted if they are deemed unnecessarily obscuring the main points of the invention. Furthermore, many terms used herein are defined in consideration of the functions within the invention and may vary depending on the intent or convention of the user or application personnel. Therefore, definitions should be based on the entire contents of this specification.

[0033] Both Embodiments 1 and 2 employ a hole-cutting method, allowing selection between hole-cutting and open-cutting modes. In Embodiment 1, the small and large cutting blades are arranged in a row, while in Embodiment 2, the large and small cutting blades are arranged circumferentially with the axis as the center. In Embodiment 3, a rotating barrier wall replaces the position adjustment knob found in Embodiments 1 and 2.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, in the pet nail trimmer of the present invention, the first body 10 and the second body 20 are connected by a rotating shaft 30. With the rotating shaft 30 as a reference, two cutting blades (large cutting blades 11 and 21 and small cutting blades 12 and 22) are formed at the front ends of the first body 10 and the second body 20, respectively. The cutting blades are adjusted to positions for hole cutting and open cutting by a position adjustment unit (position adjustment knob 40, circular blade support 27, and first tightening stop block 28).

[0036] The first body 10 and the second body 20 form the aforementioned cutting blade on the front side with the rotation axis 30 as a reference, and form handles 13 and 23 on the rear side. The aforementioned cutting blades are such that small cutting blades 12 and 22, which are approximately semi-circular, are arranged in a row at the front end, and large cutting blades 11 and 21 are arranged in a row at the rear side.

[0037] This arrangement can be interchanged. Alternatively, the arrangement can be changed and the first tightening stop 28 removed to create a single trimmer for cats and dogs. In this case, there is a disadvantage that greater force is required to cut the nails of thicker dogs, as they are further from the axis.

[0038] The small cutting blades 12 and 22 are the size of those used to cut a cat's nail (1.8mm to 2.0mm in diameter), while the large cutting blades 11 and 21 are the size of those used to cut a dog's nail (3.5mm to 4.5mm in diameter).

[0039] The large cutting blades 11 and 21 and the small cutting blades 12 and 22 are maintained in a circular shape by the position adjustment knob 40 supported by the circular blade holder 27.

[0040] The first body 10 and the second body 20 are formed with a stop block groove 14 and an internal stop block 24 so that when the handles 13 and 23 of the first body 10 and the second body 20 are gripped and tightened for trimming nails, the first body 10 and the second body 20 can only rotate within a specified angle range.

[0041] The stop block groove 14 is formed open around the rotation shaft hole 15 of the first body 10 toward the second body 20, forming concentric circles in a manner corresponding to the rotation of the inner stop block 24, and the inner stop block 24 is stopped from rotating by the blocking structure of the two side walls.

[0042] The internal stop block 24 is formed protruding from the bottom surface of the rotating shaft hole 25 of the second body 20. After being inserted into the stop block groove 14 and moving along the stop block groove 14, it stops moving by the two side walls of the stop block groove 14.

[0043] The first body 10 and the second body 20 are connected by springs to facilitate operation. For this purpose, opposing spring grooves 16 and 26 are formed inside the first body 10 and the second body 20. Springs (not shown) are installed in the spring grooves 16 and 26. The springs are inserted into the spring grooves 16 and 26 and fixed on both sides of the first body 10 and the second body 20 respectively to elastically support the first body 10 and the second body 20 (the elasticity at this time is the elasticity in the direction that allows the first body 10 and the second body 20 to open to the maximum extent above the open cut).

[0044] The following is a structure formed by the position adjustment knob 40 for fixing and for adjusting the position for hole cutting and open cutting.

[0045] The upper periphery of the rotating shaft hole 15 of the first body 10 has three levels of fixing grooves 17-1, 17-2, and 17-3, so as to adjust the knob 40 according to the fixed position of each level.

[0046] Figure 3The first-level position adjustment state formed by the first-level fixing groove 17-1 is shown, which allows the small cutting blades 12 and 22 to trim the cat's nails, but the large cutting blades 11 and 21 cannot be used to trim the nails.

[0047] Figure 4 The second-level position adjustment state formed by the second-level fixing groove 17-2 is shown, which can utilize both the large cutting blades 11 and 21 and the small cutting blades 12 and 22.

[0048] Figure 5 The third-level position adjustment state formed by the third-level fixing groove 17-3 is shown. It is the maximum opening state and is the position adjustment state used for open cutting.

[0049] A circular blade support 27 and a first tightening stop block 28 are formed around the rotating shaft hole 25 of the second body 20.

[0050] With the circular blade support 27 in the bottom support position and the adjustment knob 40 in place, the cutting blades 11, 21, 12, and 22 are kept circular. With the circular blade support 27 in the upper position of the position adjustment knob 40, the cutting blades 11, 21, 12, and 22 are adjusted to the open cutting position.

[0051] The first tightening stop block 28 is used to prevent the large cutting blades 11 and 21 from overlapping by locking them in the position adjustment knob 40. That is, when the small cutting blades 12 and 22 are used to trim the cat's nails, although the small cutting blades 12 and 22 overlap, the large cutting blades 11 and 21 will be prevented from overlapping.

[0052] The position adjustment knob 40 is rotatably mounted on the first body 10 via the knob shaft 50. It includes: a head 41 and a first locking shoulder 42, which are in direct contact with the circular blade bracket 27; and a knob shaft hole 43, which is axially engaged with the first body 10.

[0053] Furthermore, the position adjustment knob 40 includes a latch that maintains the adjustment state of each level by engaging with one of the three levels of fixing slots 17-1, 17-2, and 17-3. For example, the latch is formed by a structure comprising a ball that is elastically supported by the elastic force of an elastic member along the direction of engagement with the fixing slots 17-1, 17-2, and 17-3.

[0054] The head 41 is supported by the circular blade support 27 to position the cutting blades 11, 21, 12, 22 in a circular hole-cutting position or to move away from the circular blade support 27 to an open cutting position, so that the shape is curved (circular) so that the first tightening stop block 28 can pass naturally.

[0055] The first locking shoulder 42 is used to stop the first tightening stop block 28 from rotating.

[0056] The usage method of this embodiment is as follows.

[0057] 1. Hole cutting

[0058] 1) Use a small cutting blade

[0059] When trimming a cat's nails using the small cutting blades 12 and 22 in a perforated cutting manner, it forms... Figure 2 In the initial state shown, the latch of the position adjustment knob 40 is fixed in the first-level fixing groove 17-1. In this case, in order to perform hole cutting, the head 41 of the circular blade support 27 adjusts the knob 40 in the bottom support position so that the small cutting blades 12, 22 form a circular hole.

[0060] If the cat's nail is inserted into the hole at the desired trimming length in a manner almost perpendicular to the circular hole formed by the small cutting blades 12 and 22, and the handles 13 and 23 are tightened, then... Figure 3 As shown, the first body 10 and the second body 20 are rotated via the rotating shaft 30, causing the small cutting blades 12 and 22 to cross and trim the nails.

[0061] During this process, the first tightening stop block 28 is locked in place by the first locking shoulder 42 so that the second body 20 no longer rotates, that is, the cat's nails can be trimmed by gently tightening.

[0062] If the handles 13 and 23 are loosened, the first body 10 and the second body 20 will rotate back to their initial positions through elasticity, thereby causing the cutting blades 11, 21, 12, and 22 to open and return to a circular shape.

[0063] 2) Use a large cutting blade

[0064] When trimming a dog's nails using the large cutting blades 11 and 21 in a hole-cutting manner, the position adjustment knob 40 is fixed in the second-level fixing groove 17-2. In this case, the circular blade support 27 is locked at the bottom of the head 41 of the position adjustment knob 40, so that the large cutting blades 11 and 21 form a circular hole.

[0065] If the dog's nail is inserted into the hole at the desired trimming length in a manner almost perpendicular to the circular hole formed by the large cutting blades 11 and 21, and the handles 13 and 23 are tightened, then... Figure 4 As shown, the first body 10 and the second body 20 rotate via the rotating shaft 30, causing the large cutting blades 11 and 21 to cross and trim nails. In this case, when the second body 20 rotates due to the fixed position of the position adjustment knob 40, the first tightening stop block 28 passes through the first locking shoulder 42 of the position adjustment knob 40 to make the large cutting blades 11 and 21 completely cross, and then stops through the stop block hole 14 and the inner stop block 24.

[0066] If the handles 13 and 23 are loosened, the first body 10 and the second body 20 will rotate back to their initial positions through elasticity, thereby causing the cutting blades 11, 21, 12, and 22 to open and return to a circular shape.

[0067] 2. Open cutting

[0068] like Figure 5 As shown, the position adjustment knob 40 is fixed in the third-level fixing slot 17-3. The third level is the position where the head 41 of the position adjustment knob 40 does not interfere with the rotation of the circular blade support 27.

[0069] Following the diameter of the nail will allow handles 13 and 23 to open properly. Figure 5 The diagram shows the state of maximum opening with the inner stop block 24 in contact with one side wall of the stop block groove 14.

[0070] In this way, the first body 10 and the second body 20 will rotate and open like scissors, so that the small cutting blades 12 and 22 and the large cutting blades 11 and 21 will each be in a state where the front side is open. In this case, the first body 10 and the second body 20 only open at the angle that the internal stop block 24 is constrained by the wall surface of the stop block groove 14, and will not open further.

[0071] After inserting the nail into the space between the large cutting blades 11, 21 or the small cutting blades 12, 22 from the open front side, trim the nail by tightening the handles 13, 23 so that the large cutting blades 11, 21 and the small cutting blades 12, 22 cross.

[0072] Example 2

[0073] like Figure 6 As shown, in this embodiment, the large cutting blades 11 and 21 and the small cutting blades 12 and 22 are arranged along the circumferential direction with the rotation axis 30 as the reference. Compared with Embodiment 1, there is no difference between the inner and outer sides.

[0074] The structures of the large cutting blades 11 and 21 and the small cutting blades 12 and 22 are the same as those of the cutting blades in Example 1 (a structure that cuts by making the two cutting blades cross each other). Both open cutting and hole cutting described in Example 1 can be achieved.

[0075] 1. Hole cutting

[0076] 1) Use a small cutting blade

[0077] Figure 7The illustration shows the use of small cutting blades 12 and 22 to trim a cat's nails. The position adjustment knob 40 is fixed in the first-level fixing slot 17-1. After inserting the cat's nail into the hole of the small cutting blades 12 and 22 that maintain a circular shape, the cutting is performed. The specific cutting operation is the same as in Embodiment 1 above. The first body 10 and the second body 20 will rotate to a width through which only the small cutting blades 12 and 22 make the cut.

[0078] 2) Use a large cutting blade

[0079] like Figure 8 As shown, the position adjustment knob 40 is fixed in the second-level fixing slot 17-2. After inserting the dog's nail into the hole of the large cutting blade 11, 21 that maintains the round shape, the cutting is performed. The specific cutting operation is the same as in Example 1.

[0080] 2. Open cutting

[0081] like Figure 9 As shown, the position adjustment knob 40 is fixed in the third-level fixing slot 17-3. If the handles 13 and 23 are opened, the large cutting blades 11 and 21 and the small cutting blades 12 and 22 will open and the front side will be open. After inserting the dog's nail or cat's nail from the open front side of the large cutting blades 11 and 21 and the small cutting blades 12 and 22 to the rear side, the nail will be cut.

[0082] Compared with Example 1, the use of the large cutting blades 11 and 21 is more convenient for open cutting because there is no structure that prevents the nail from being inserted into the front of the large cutting blades 11 and 21.

[0083] On the other hand, although not shown in the accompanying drawings, the present invention can be configured such that the small blade and the large blade are arranged along the circumferential direction, and the small blade is configured to be used for hole cutting, while the large blade can be configured to be used for hole cutting and open cutting.

[0084] The difference is that the large cutting blade can utilize a structure that enables both hole-type and open-type cutting, as in Embodiments 1 and 2, while the small cutting blade uses a circular cutting edge to cut the cat's nails only in a hole-type cutting manner.

[0085] Example 3

[0086] like Figure 10 and Figure 11 As shown, in this embodiment, the position adjustment knob 40 described in the above embodiment is removed, and a rotation barrier wall 18 is formed above the handle 13 adjacent to the outer periphery of the rotation shaft hole of the first body 10 to prevent the cutting blades 11, 21, 12, and 22, which are respectively formed in a semi-circular shape, from opening.

[0087] The rotating barrier 18 is a structure that constrains (stops) the rotation of the circular blade support 27 formed in the second body 20. When the circular blade support 27 contacts the rotating barrier 18, the cutting blades 11, 21, 12, and 22 formed in the first body 10 and the second body 20 are aligned and form a pair of circles, into which cat or dog nails are inserted for hole-type cutting.

[0088] like Figure 12 As shown, the circular blade support 27 and the rotating barrier wall 18 can also be applied to the configuration where the cutting blades 11, 21, 12, and 22 are arranged along the circumferential direction.

[0089] And, as Figure 13 In the example shown, the small cutting edges 11 and 21 form circles, while the large cutting edges 12 and 22 form semicircles respectively.

Claims

1. A pet nail trimmer, characterized in that, Including the first entity and the second entity, The first and second bodies are joined by a rotating axis. Based on the aforementioned rotating axis, intersecting cutting blades are formed on the front side in an opposing manner, and a handle is formed on the rear side. A spring is provided so that the handle and cutting blade open about the rotation axis. A position adjustment knob is rotatably mounted on a handle adjacent to the outer periphery of the rotating shaft hole of the first body, and a circular blade support protrudes from the outer periphery of the rotating shaft hole of the second body. The aforementioned cutting blade consists of a small, semi-circular cutting edge and a large, semi-circular cutting edge.
