Description

Hair care scissor assembly with detachable dovetail coupling {HAIRDRESSING SCISSOR ASSEMBLY HAVING DETACHABLE DOVETAIL CONNECTION}

The present invention relates to a scissor assembly for hair care consisting of a plurality of scissors detachably joined to each other by a detachable dovetail coupling for special hair cutting.

The hairdresser trims the client's hair with a variety of techniques including trimming, thinning, layering, and the like. The hairdresser sometimes has to hold several scissors in one hand to scrub the hair or stratum the hair to get the desired hairstyle.

While working with a plurality of scissors in one hand, the user should keep these plurality of scissors at regular intervals and operate under the same conditions. Multiple scissors must be opened and closed at the same time to get a neat and beautiful hairstyle. However, these plurality of scissors cannot be operated at the same time because they are difficult to handle the plurality of scissors held by the finger simply by the user's thumb and index finger. Therefore, the plurality of scissors may sometimes shift from one another and be different from each other. This adversely affects the results of hair care, and this problem is more severe when the user is inexperienced. The user sometimes has difficulty in difficulty of operation in addition to the numerical limitation when operating a plurality of scissors.

U.S. Patent No. 6,192,590 and Applicant's U.S. Patent Application Serial No. 09 / 617,713, filed on February 27, 2001, describe a hair care scissors assembly for solving the above problem. However, there is a problem of failure and cost since the slots of the coupling member and the connection block are formed in an L-shape to join the plurality of scissors.

It is an object of the present invention to provide a scissor assembly for hair care consisting of a plurality of scissors detachably joined to each other by a detachable dovetail coupling for special hair cutting.

With reference to FIG. 1, a first embodiment of a hair care scissors assembly according to the invention generally comprises a plurality of scissors 1 having first and second cutting members each pivoted by a pivot 30. do. The first cutting member has a first handle 11 on its one end and a first blade 10 on its other end. The second cutting member has a second handle 21 on one end thereof and a second blade 20 on the other end thereof. Each blade 10, 20 has a tip 16, 26. The first and second cutting members are pivoted to each other at their middle portions. Of course, each handle 11, 21 has an opening (without reference numeral) for the thumb or index finger of the user.

The at least one first handle 11 and the second handle 21 are formed thereon from the first side portions 11a and 21a to the second side portions 11b and 21b facing the first side portions 11a and 21a. It has a through hole 12 that extends. At least one coupling block 40 is firmly mounted in the through hole 12 to couple these two scissors 1. In this embodiment, the first handle 11 and the second handle 12 have through holes 12 formed therein to receive the respective coupling blocks 40.

Referring to FIG. 2, each coupling block 40 includes a dovetail groove 41 of the first side and two dovetail blocks 43 and 45 formed on the second side facing the first side. In addition, two spaced apart lateral grooves 42 are formed on the first side of each coupling block 40 to intersect the dovetail grooves 41, thereby causing the dovetail grooves 41 to be coupled to the first coupling portions 41a. ), The first crossing portion 41b, the second coupling portion 41c, the second crossing portion 41d, and the third coupling portion 41e. When each coupling block 40 is mounted in each through hole 12, as shown in FIG. 1, the dovetail blocks 43 and 45 may have second sides 11b and 21b of the handles 11 and 21. It protrudes outwards and the first side of the coupling block 40 is flush with the first side 11a, 21a of each handle 11, 21.

When combining one scissors 1 with another scissors 1, the dovetail blocks 43 and 45 of each coupling block 40 of one scissors 1 are shown in FIG. It is inserted into the insertion grooves 41b and 41d of each coupling block 40 of the other scissors 1. Then, the right scissors of the two adjacent scissors 1 are moved upward with respect to the left scissors of the two adjacent scissors 1, so that the dovetail of each coupling block 40 of the right scissors of the two adjacent scissors 1 Blocks 43 and 45 may remain engaged with the first and second engagement portions 41a and 41c of each coupling block 40 of the left scissors of the two adjacent scissors 1, which is illustrated in FIG. 4. As shown, the tips 16 and 26 of the hair clipper 1 form a hair clipper assembly that is aligned at the same height along a straight line. Alternatively, the right scissors of the two adjacent scissors 1 are moved downward with respect to the left scissors of the two adjacent scissors 1, so that of each coupling block 40 of the right scissors of the two adjacent scissors 1. The dovetail blocks 43, 45 may remain engaged with the second and third coupling portions 41c, 41e of each coupling block 40 of the left scissors of the two adjacent scissors 1, thereby As shown in FIG. 5, the tips 16 and 26 of the hair clipper 1 form a hair clipper assembly that is aligned at different heights along an oblique line.

Figure 6 illustrates a second embodiment of a scissor assembly for hair care, the joining block being different from the first embodiment. In the present embodiment, as shown in FIG. 7, each coupling block 50 has a dovetail groove 51 formed on the first side and a dovetail block 53 formed on the upper end of the second side opposite to the first side. Include. As shown in FIG. 8, the dovetail groove 51 is positioned below the dovetail coupling part 55 and the dovetail coupling part 55 and has the same width as the maximum width of the dovetail coupling part 55. It includes an insertion unit 52.

When combining the scissors 1 with the other scissors 1, the dovetail block 53 of each coupling block 50 of one scissors 1 is the other one, as shown in FIG. Is inserted into the insertion groove 52 of each coupling block 50 of the scissors 1. Then, the right scissors of the two adjacent scissors 1 are moved upward with respect to the left scissors of the two adjacent scissors 1, so that the dovetail of each coupling block 50 of the right scissors of the two adjacent scissors 1 Block 53 may be held in combination with the dovetail coupling portion 55 of each coupling block 50 of the left scissors of the two adjacent scissors (1), thereby for hair care as shown in FIG. The tips 16, 26 of the scissors 1 form a hair care scissors assembly that is aligned at the same height along a straight line.

FIG. 11 illustrates a third embodiment of a scissor assembly for hair care, the joining block being different from the second embodiment. In this embodiment, as shown in FIG. 12, each coupling block 60 has a dovetail groove 61 formed on the first side and a dovetail block 63 formed on the lower end of the second side opposite to the first side. Include. The dovetail groove 61 includes a dovetail coupling portion 65 and an insertion portion 62 positioned above the dovetail coupling portion 65 and having a width equal to the maximum width of the dovetail coupling portion 65.

When combining one scissors 1 with another scissors 1, the dovetail block 63 of each coupling block 60 of one scissors 1 is the other one, as shown in FIG. 13. Is inserted into the insertion groove 62 of each coupling block 60 of the scissors 1. Then, the right scissors of the two adjacent scissors 1 are moved upward with respect to the left scissors of the two adjacent scissors 1, so that the dovetail of each coupling block 60 of the right scissors of the two adjacent scissors 1 Block 63 may be held in combination with the dovetail coupling portion 65 of each coupling block 60 of the left scissors of the two adjacent scissors (1), thereby for hair care as shown in FIG. The tips 16, 26 of the scissors 1 form a hair care scissors assembly that is aligned at different heights along the diagonal lines.

The hair clipper 1 according to the present invention can be detachably coupled to each other to form a hair clipper assembly, the tip of which is aligned at the same or different heights to perform various hair cutting functions.
