Description

[Detailed explanation of the idea] The present invention relates to improvements in spring combs.

As shown in FIG. 1, a conventional spring comb includes a large number of comb teeth bodies 1 which are formed by bending a metal wire and are arranged in parallel. It is well known that the comb has a loop-shaped base 2 formed by the comb, and is expandable and retractable in the direction in which the comb teeth continue.

However, in this conventional example, when the comb is inserted into the hair during use, if the hair enters only between the comb tooth bodies 1 and 1, there is no problem in inserting and pulling out the comb.
When hair enters through the gap created between the loop-shaped bases 2 and 2 as the comb extends, the entered hair gets entangled deeply with the tip of the comb tooth body 1 when the comb is pulled out from the hair, resulting in hair loss. There is a problem that it causes hair breakage.

In this regard, the above-mentioned problem can be solved by closing the gap between each loop-shaped base 2, 2 that occurs when the comb is extended.

Therefore, as a first option, it is considered that the elastic thread body is inserted through the entire loop-shaped base 2, but when the comb is extended, the loop-shaped base 2 itself also extends and opens between each comb tooth body 1. Therefore, there is a problem that the elastic thread simply inserted through the opening may be misaligned, such as slipping down from the opening.

As a second option, it is also possible to glue or sew a tape-like rubber material over the continuous loop-shaped base 2;
If adhesive or sewing is used, it is not only difficult to manufacture and expensive, but also the loop-shaped base 2 itself is elastically deformed when the comb is extended as described above. There is a problem in that the rubber material is forced to elongate unreasonably following the elastic deformation, causing the rubber material to fall off due to early fatigue of the adhesive or sewing thread.

In view of the above, the present invention has been developed by knitting an elastic thread body on a loop-shaped base, so that the elastic thread body can be attached to a comb extremely simply and easily by hand. It is an object of the present invention to provide a spring comb that is firmly attached to the base and does not shift at all, thereby solving all of the above problems.

Therefore, the characteristic feature of the comb is that the knitted elastic thread is inserted through the continuous loop-shaped base of the comb, and the loops are connected to the loop-shaped base in a continuous manner. It's about being prepared.

The embodiment of the present invention will be described below in detail with reference to the drawings.The spring comb 3 itself is similar to the conventional example shown in the first drawing above, and is made by bending metal spring wires and arranging them continuously in parallel. It is provided with a large number of comb-tooth bodies 4, and a loop-shaped base 5 for bending and bending the wire at the continuous part of each comb-teeth body 4, and is expandable and contractible in the direction in which the comb-teeth bodies 4 are continuous. There is.

FIG. 2 shows a first embodiment of the present invention, in which an elastic thread 6 is inserted through the continuous loop-shaped base 5 to perform so-called chain knitting, and as will be described later, each loop-shaped base is 5 and arranged on the front surface of the base 5, and the thread body 6 that connects the adjacent loops 7 is connected to the back surface of the loop-shaped base 5. A hooking portion 8 is constituted by which the loop 7 is hooked onto the base portion 5 by being entangled with the base portion 5.

The method of knitting the elastic thread body 6 will be explained based on FIG. A knitting needle 9 is inserted into the loop-shaped base 5a to lock it to the elastic thread 6, and the knitting needle 9 pulls out the thread 6 from the loop-shaped base 5a to form a fastening loop 10, as shown in FIG.
Next, as shown in Figure III, thread body 6 is further attached to knitting needle 9 in this state.
is locked and pulled out from the fastening loop 10 as shown in FIG. IV to form the first loop 7.

At this time, the fastening loop 10 contracts and the base of the first loop 7 is fixed to the loop-shaped base 5a.

Thereafter, as shown in FIG.
As shown in FIG. VI, the yarn body 6 is pulled out from the loop-shaped base 5b and the first loop 7 by the knitting needle 9 to form the second loop 7.

The first loop 7 and the second loop 7 are connected by an elastic thread body 6, and the thread body 6 serving as the connecting part forms a hanging part 8, and this hanging part 8 and the first loop 7 The loop-shaped base 5b
are sandwiched from the front and back.

Next, as shown in FIG. VII, the knitting needle 9 inserted through the second loop 7 is further inserted into the adjacent loop-shaped base 5C, and
As shown in (2) in the same figure, the yarn body 6 is pulled out from the loop-shaped base 5C and the second loop 7 by the knitting needle 9 to form the third loop 7.

At this time, the second loop 7 is a hanging portion 8 formed by the continuous thread body 6.
Adjacent loop-shaped bases 5b and 5C are sandwiched between them, and thereafter, the same operations as those described above may be repeated to sequentially knit the loops 7 on the loop-shaped base 5.

According to this embodiment, in the normal state when the spring comb 3 is not extended, each loop-shaped base 5 is in contact with or close to each other, and each loop-shaped base 5 forms a complete loop and has an opening. Therefore, the elastic thread body 6 will not be displaced from the loop-shaped base 5.

On the other hand, when the comb 3 is used in an extended state, the continuous elastic threads 6 are extended and tightened, so that each loop 7 is deformed into an oval shape and comes into close contact with the loop-shaped base 5. The hanging portion 8 which is continuous with the loop-shaped base portion 5 is also stretched and tensed and comes into close contact with the loop-shaped base portion 5 from the opposite side.

Therefore, depending on the extension of the comb 3, the loop 7 and the hooking part 8 are
The loop-shaped base 5 is more strongly pinched from the front and back sides, so even if the loop-shaped base 5 has an opening due to deformation during stretching, the elastic thread 6 will pass through the opening to form the loop-shaped base 5. There is no possibility that the comb tooth body 4 will be displaced from the base 5 and displaced in the distal direction of the comb tooth body 4.

FIG. 4 shows a second embodiment of the present invention, in which an elastic thread body 6 is inserted through a continuous loop-shaped base 5 and is knitted.
Basically, a series of loops 7' are formed and arranged corresponding to the front surface of the loop-shaped base 5 by the thread body 6 in the same manner as in the above embodiment.
and a hooking part 8 which connects these loops 7' and which extends to the back surface of the loop-shaped base part 5.

The method of knitting the elastic thread body 6 in this second embodiment will be explained based on FIG. After that, as shown in FIG. 5I, a knitting needle is inserted into the loop-shaped base 5a and locked to the elastic thread body 6, and the knitting needle 9 is inserted as shown in FIG.
, the thread body 6 is pulled out from the loop-shaped base 5a to form a fastening loop 10', and then the thread body 6 is further secured to the knitting needle 9 in this state as shown in FIG. It is pulled out from the loop 10' to form a first loop 7'.

At this time, the fastening loop 10' contracts and fixes the base of the first loop 7' to the loop-shaped base 5a, and the operations shown in FIGS. It is the same as the one above.

Thereafter, the knitting needle 9 inserted through the first loop 7' is inserted into the adjacent loop-shaped base 5b as shown in FIG. The thread body 6 is pulled out from the loop-shaped base 5b by the winding loop 1.
1, and as shown in FIG. 11 and pulled out from the first loop 7' to form a second loop 7'.

At this time, the winding loop 11 contracts as shown in (3) in the same figure, thereby forcing the hooking portion 8' that winds the base of the second loop 7' onto the loop-shaped base 5b.

Thereafter, the knitting needle 9 inserted through the second loop 7' is further inserted into the adjacent loop-shaped base 5C and latched to the elastic thread body 6, as shown in (3) in the same figure, and then pulled out from the loop-shaped base 5C and the same. As shown in FIG. When the thread 6 is pulled out from the winding loop 11 and the second loop 7' to form the third loop 7' as shown in (2), the winding loop 11 contracts and the base of the third loop 7' is pulled out from the winding loop 11 and the second loop 7'. This makes the hook part 8' that wraps around the shaped base part 5C.

After that, the same operation as above is repeated to sequentially form the loop-shaped base 5.
It is sufficient to form a loop 7'.

According to this embodiment, when the spring comb 3 is in use in an extended state, the continuous elastic threads 6 are extended and tensioned, so that each loop 7' is deformed into an oval shape and is continuous with this. The hooking portion 8' is tensioned to securely wrap each loop 7' around each loop-shaped base 5.

Therefore, as the comb 3 expands, the hooking portion 8' wraps the loop 7' around the loop-shaped base 5 more tightly.
Even if the loop-shaped base 5 has an opening due to deformation during elongation, the elastic thread body 6 will escape from the loop-shaped base 5 through the opening, causing a positional shift in the direction of the tip of the comb tooth body 4. There isn't.

As a result of the present invention configured as described above, the elastic thread body 6 is knitted by being inserted through the loop-shaped base 5 of the spring comb 3.
, the hair does not enter the gap between the loop-shaped bases 5 and 5 that occurs as the comb 3 extends during use, and therefore, when the comb 3 is pulled out from the hair, the hair that has entered the comb does not enter the gap between the loop-shaped bases 5 and 5 as the comb 3 extends. It does not get entangled with the tip of the tooth body 4 and cause hair loss or hair breakage.

Particularly, according to the present invention, the elastic yarn body 6 can be simply knitted by chain knitting or fine knitting to form a loop 7 corresponding to the loop-shaped base 5 and disposed in front of the base 5.
7' continuously, and a hooking part that hangs the loop 7.7' on the base 5 by being entwined with the back surface of the loop-shaped base 5 by a portion of the thread body 6 that interconnects adjacent loops. 8,
8', there is an advantage that the thread body 6 can be attached to the loop-shaped base 5 very easily by knitting the thread body 6, and moreover, as described above, the thread body 6 can be attached to the loop-shaped base 5 in front of the loop-shaped base 5. The loops 7.7' of the elastic thread 6 are kept loose to some extent, and as the comb 3 stretches, the loops 7.7' easily follow and stretch with suitable elasticity. When extended, the hooking portions 8, 8'
The loops 7 and 7' are formed at equal pitches and are wrapped around the back surface of the loop base 5 so that the connecting portions of the loops 7 and 7' corresponding to each loop base 5 are connected. Because it functions to fix it even more strongly,
The elastic thread body 6 is excellent in that there is no displacement of the elastic thread body 6 from the loop-shaped base portion 5 toward the distal end of the comb tooth body 4.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and as long as the elastic thread body is knitted with a loop and a hanging part, the thread body can be layered in multiple layers around the loop-shaped base. It is free to organize.
