Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a base fabric for a cuff band of a blood pressure monitor and a method for manufacturing the same.

Conventional art The cuff band of a blood pressure monitor generally consists of an upper base fabric and a lower base fabric formed in the same shape, and a male side fastener and a female side fastener are sewn to one or both of the base fabrics. , the respective base fabrics are stacked so that the male side zipper and the female side zipper are on the front side, and each of the base fabrics is sewn around its periphery leaving an open edge on one side to form a bag shape, and the bag is formed into a bag. After a rubber pouch for injecting air into the bag is housed in the bag from the opening edge, the opening edge is sewn to seal the upper base fabric and the lower base fabric.

Problems to be Solved by the Invention However, in the cuff band formed in this way, the base fabric, the male side fastener, and the female side fastener are separate, and the male side fastener and the female side fastener are attached directly to the surface of the bag. Since they are sewn together, the portions to which the hook-and-loop fasteners are attached become thick, making handling inconvenient.

In addition, since the front J shida cuff band is sewn using ten base fabrics and lower base fabrics, each formed in the same shape, it is complicated and requires a lot of manufacturing processing and dimensioning work. Products made using such processes also end up being expensive.

A first object of the present invention is to provide a base fabric from which a cuff band for a blood pressure monitor can be manufactured which is free from thickening and is easy to handle.

A second object of the present invention is to provide a method for manufacturing a base fabric for the cuff band of a blood pressure monitor, which can be obtained at low cost.

Means for Solving the Problems The present invention has been made in view of the above points, and consists of a rectangular base fabric composed of chain stitch, tricot stitch, and single cord knitting structures. A plurality of loop-shaped engaged elements formed by raising piles made of sinker loops of the single cord knit are formed on substantially the entire surface of the surface on one side of the intermediate line extending in the longitudinal direction from the center part in the width direction. ,
One of the above problems is solved by attaching a synthetic resin to at least the back surface of the portion of the base fabric having the loop-shaped engaged element.

Further, the present invention includes a knitting yarn of chain stitch, tricot stitch, and single cord stitch, and has a plurality of piles formed of sinker loops of single cord stitch on substantially the entire surface and forming a loop-shaped engaged element. Continuously knitting a knitted fabric having regions and regions having no pile alternately in the longitudinal direction,
By raising the pile to form a plurality of loop-shaped engaged elements, and attaching a synthetic resin to the back surface of the knitted fabric at least in the area where the engaged elements are present, the above-mentioned Solve the other problem.

Example The present invention will be described below based on embodiments shown in the drawings.

Examples of Base Fabrics The base fabric (1) shown in Figure 1 is made of synthetic m-knit yarns, and is made of chain knitting knitted into one wale, tricot knitting spanning two wales, and single cord knitting spanning at least four wales. The first area organized by an organization such as
2) and a second area (3>).

The first area (2) is located on the left side of the intermediate line (X) extending longitudinally through the widthwise central part of the base fabric (1), and is located at the intermediate i
Both the area portions of the side edge extending on the right side along s<x> and the outer line extending on the left side parallel to the median line (
, 4), and the rest is the area portion with the loop portion on the surface (
5).

The area that becomes the ears (4, 4) is composed of chain stitch, tricot stitch, and single cord stitch yarns, and the sinker loop of the single cord stitch is held down by the chain stitch yarn to create a flat shape. It is on the surface.

The area (5) having loops on its surface is made up of tricot knitting and single cord knitting yarns, and the surface of the area (5) has each pile made of single cord knitting sinker loops. A plurality of loop-shaped engaged elements (6) are formed which can be pulled up to form a hook-and-loop fastener.

The second area (3) is located on the right side of the intermediate line (X) and is formed in a rectangular shape. This second area (3) is
It is composed of chain knitting, tricot knitting, and single cord knitting yarns, and the sinker loop of the single cord knitting is pressed down by the chain knitting yarn to form a substantially flat surface.

In the illustrated example, the chain-line knitting yarn in the second region (3) is knitted over the entire area and has an almost flat surface, but the side edges extending adjacently along the midline (X>) It may be knitted only in both areas of the outer edge extending parallel to the line (X),
Alternatively, it may be woven intermittently in the width direction of the second area (3). In each of these lifting platforms, a small pile portion formed by the sinker loop of the single cord is raised on the surface of the second area (3). Furthermore, the second region may be constructed by knitting a single-cord knitting yarn that spans three wales, and in this case also, a small pile portion due to the sinker loop of the single-cord knit appears on the surface.

It is not necessary that all the knitting yarns constituting the first section (2) and the second section (3) be synthetic fiber yarns, and at least each knitting yarn of chain line and tricot knitting can be replaced with natural fiber yarns other than synthetic fiber yarns. , artificial fiber yarn may also be used.

In this way, the base fabric (1) consisting of the first area (2) and the second area (3) is coated with a synthetic resin material such as polyvinyl chloride or polyester on the entire back surface of the base fabric (1). A resin (7) is applied thereto, whereby the engaged element (6) of the area (5>) is maintained in a raised state.

Note that the synthetic resin (7) processed with resin does not necessarily have to be formed on the entire back surface of the base fabric (1), but rather on the first area (2).
), particularly only on the back surface of the area (5).

Example of manufacturing method for base fabric First, as shown in FIGS. 4 and 5, a knitted fabric (11) that is continuous in the longitudinal direction is separated into pile areas (12) and flat areas (13) in the lateral direction. Organize in an alternating manner.

As shown in FIGS. 2 and 3, such a knitted fabric (11) is knitted with tricot knitting yarn (L2) and single cord knitting yarn (Lt) in pile section 14 (12). In the flat area (13), the chain line knitting yarn (Ll)
It is obtained by knitting with a tricot knitting yarn (L2) and a single cord knitting yarn (li). In addition, in Figure 2, (A) is 1-0/ which is knitted into one wale.
O-1 chain stitch yarn (I-+), (B) spans two wales 1-0/1-2 tricot stitch yarn (2), (C) spans four wales 1-0 across
/ 3-4 single cord knitting yarns (Ls) are shown respectively.

In addition, the pile area (12) of the knitted fabric (11) has a tricot knitting yarn (L2) as the base texture, and as shown in Figure 9, a single cord knitted sinker loop (Lgl) is on the surface. It is starting to rise significantly. Further, the flat area (13) is held down by the single cord knitting sinker loop (LSI1) by the chain knitting yarn (Ll) and does not rise to the surface and is substantially flat.

The knitted fabric (11) in which the pile areas (12) and flat areas (13) are knitted alternately can be easily produced using appropriate synthetic fiber yarns using a knitting machine such as a tricot knitting machine, a double raschel machine, or a circular knitting machine. can be organized.

In addition, the above-mentioned flat area (13) is made of chain knitting yarn (Ll
) is knitted in the entire area, but as shown in Figure 11, it is also possible to knit two rows of chain knitting yarn (Ll) on both sides of the knitting yarn (Ll) and knit it in every other row in the remaining area. good. In this case,
A small pile of single-cord sinker loops (LSI) floats on the surface.

Next, a single cord knitted sinker loop (L
, 3+) are pulled up in the floating direction as shown in FIG. As a result, the pile area (12), as shown in FIG. A plurality of loop-shaped engaged members (15) are formed which are pulled up to a large extent and become hook-and-loop fasteners.

In addition, as the pile is pulled up, the width of the pile area (12) is contracted in the direction of reduction, so the pile area [(1
2) Take into account the width dimension by pre-caulking and covering the knitting as much as possible.

As shown in FIG. 6, after the pile in the pile area (12) is raised to form a loop-shaped engaged element (15), the seventh
As shown in the figure, a synthetic resin (16) is applied to the entire back surface of the knitted fabric (11) by resin processing.

This synthetic resin (16) can be attached by coating the back side of the knitted fabric (11) with a solution of dissolved synthetic resin such as polyvinyl chloride or polyester and then drying it. Knitted cloth (11
) may be formed by thermally adhering it to the back surface of the
The synthetic resin may be melt-extruded and adhered to the back surface of the knitted fabric (11).

Further, this resin treatment does not need to be applied to the entire back surface of the knitted fabric (11), and may be applied only to the back surface of the pile area (12).

Next, knitted fabric (11) with synthetic resin (16) attached to the back side.

Cut with Y). In this way, the cut knitted fabric (11
a) is flat on one side R (1
It consists of one pile area (12a) containing 3= ) and one flat area (13a), and is then cut at a predetermined position in the longitudinal direction to obtain the base fabric shown in Figure 1. . That is, the area on the left side (12a
) corresponds to the first area (2) of the base fabric (1), and the area on the right (13a>) corresponds to the second area (3) of the base fabric (1)
It will be equivalent to .

The above-mentioned knitted fabric (11) is 1, as shown in FIG.
) (B) and (C) three types of knitting yarns (La, C2.

C3), but four types of different knitting yarns (La, C2) with different knitting structures as shown in Fig. 12 are used.

La, Ls) may be knitted with a warp knitting structure as shown in FIG.

In addition, in Fig. 12, (A) is a 1-0/0-1 chain stitch knitting yarn (L, ), (B) knitted into one yarn.
(C2) is a 1-0/1-2 tricot knitting yarn knitted into two wales (C2), and (C) is a 1-0/2-3 single cord knitting yarn (C4) that is knitted into two wales.
), (D) is 1-074-5 spanning five wales
The knitting yarns ([5)] of each single cord knitting are shown respectively.

Each knitting yarn of such a knitting structure (La, C2, C4, 1s
) The knitted fabric (21) knitted by the combination of
As shown in the figure and FIG. 15, the area (22) with a large raised pile portion and the area (22) with a small “1°/, : /<
(/L = part t @ t a area (23) e lateral direction
To explain this in more detail, the area (22) having a large raised pile part is knitted in a state in which the knitting yarns of tricot knitting (C2 ) and the single cord knitting yarn (L, ) overlap to form a sinker loop of the single cord knitting yarn (L, ).
The small pile area (2
4), the tricot knitting yarn (C2) and the single cord knitting yarn (Ls>) overlap and the sinker loop (Lad) of the single cord knitting yarn (Ls) rises to the surface. It consists of a pile area (25), and both side edges of this area (22) each have two rows of chain knitting yarn (
La ) is knitted to form a reinforced ear area portion (26) with no pile on the surface, and further the small pile area [(2
4) and the large pile area (25), a boundary area portion (27, 27>) without pile is formed on the surface where two rows of chain knitting yarns (12) are knitted. Next, in the area (23) having a small floating pile part, the knitting yarn of the tricot knit (C2) and the knitting yarn of the single cord knit (C4) overlap in the central area, resulting in the knitting of the single cord knit. The sinker loop (Lad> of the yarn (C4) is small and raised on the surface, and the edges on both sides of the central area are each knitted with two rows of chain stitch yarn (La). Reinforced ear area without pile on surface (28
, 28).

Both the ear areas (26) and (28) have no piles on their surfaces and are substantially flat, so both areas (26) and (28)
It can be used as a mark to distinguish between 2) and (23), and since the boundary area (27) in area (22) also has no piles on the surface and is approximately flat, the small pile area ( 24) and the large pile area (25), and has the advantage that the range in which the C1 pile is pulled up into the loop-shaped engaged element that becomes the hook-and-loop fastener can be easily determined.

Further, the ear area portions (26) and (28) are the thirteenth ear area portions (26) and (28).
They are connected by a connecting thread (C6) indicated by a dotted line in the figure, and this connecting part is thinner than other parts as shown in FIG. 19.

In addition, since the width dimension of the area (22) in the knitted fabric (21) knitted in this way is contracted when the pile is raised to form a loop-shaped engaged element, other It is larger than the width of area (23).

As shown in FIG. 16, the above-mentioned knitted fabric (21) has a sinker loop (Ls + ) of the single cord in the large pile area in the area (22) having a large raised pile area. A plurality of loop-shaped engaged members (30) are formed to serve as hook-and-loop fasteners, hook-and-loop fasteners, and fasteners.

As shown in FIG. 17, the knitted fabric (21) in which the loop-shaped engaged element (30) has been formed is coated with a synthetic resin (31) on its entire back surface by resin processing, and then,
As shown in FIG. 17, cutting is performed at the position of symbol (Y). The knitted fabric (21) cut in this way is cut at appropriate positions in the longitudinal direction to obtain a base fabric as shown in FIG. That is, when viewed from FIG. 18, the area (22a) on the left corresponds to the first area (2) of the base fabric (1), and the area (23a) on the right corresponds to the second area (2) of the base fabric (1).
This corresponds to area (3).

As mentioned above, since the connecting part between the two areas (22) and (23) is thinner, it is necessary to cut and bend as shown in Figures 17 and 18 [(in Figure 18)]. It has the advantage that it serves as a mark for bending at the X) portion, and also facilitates cutting, bending, etc.

Embodiments of Cuff Band To obtain a cuff band for a blood pressure monitor from the base fabric (1) knitted according to the embodiments shown in FIGS. 2 to 11 or the embodiments shown in FIGS. 12 to 19, First, as shown in FIG. 20, a male side fastener (43) having a hook-shaped engager (41) formed on a base fabric (42) is sewn to one longitudinal end of the second region (3). .

Next, as shown in FIG.

ll! = h8”, then between the first and second sections (2, 3) and the male side fastener (
Attach a rubber pouch (44) to the end opposite to the end where the
).

After that, the first area (2) and the second area (3) of the base fabric (1)
As shown in FIG. 22, each peripheral portion (45, 46, 47) excluding the intermediate line (X) and the approximately central portion (48) are heated by heating means such as ultrasonic waves, high frequency waves, and a heater. Melt bonding keeps the rubber bladder (44) from moving within it.

As a result, as shown in FIG.
The parts of the synthetic resin (7) excluding the pipe (44a) are melted and bonded to each other, and the peripheral parts (46, 47) and the central part (48) extending in the width direction of the base fabric (1) are bonded together. As shown in Figures 24 and 25, synthetic resin (7
) are melted and fused together, and the engaged element (6) at that portion is melted so that the front side of the base fabric (1) becomes flat.

FIG. 26 shows an example of a cuff band formed in this way, and this cuff band is wrapped around an arm or leg, etc., with the area portion (5) having a plurality of engaged elements (6) as the surface. Attach the engager (41) of the male side fastener (43) to the area (
It can be fixed by hooking it onto the engaged element (6) of 5).

In addition, when the base fabric obtained from the knitted fabric knitted in the knitting structure shown in FIG. 11 or FIG. 13 is used, as shown in FIG. (L9+, Lt 1 > exists on the back side of the cuff band, so each of the sinker loops (L3
+ , Lt + ) has the advantage that it fits the skin of the arms or legs, giving a soft feel without giving a stiff feeling.

In addition, what is shown in FIGS. 28 to 30 is based on the base fabric (1
) is shown below.

First, as shown in FIG. 28, the male side fastener (43) is attached to the longitudinal end of the first section (2).
Then, as shown in FIG. 29, a rubber bladder (44) is stored between the first and second areas (2, 3), and the first
The zone (2) and the second zone (3) are melted and joined by heating means, and an annular ring (49) is attached to the end opposite to the end to which the male side fastener (43) is sewn.

As shown in FIG. 30, this cuff band is made by passing the end of the male side fastener (43) through the ring (49) and rolling it back to the area (5) side.
) to the engaged element (41) of the area (5) to the engaged element (6) of the area (5)
Just hang it on and fix it.

In addition, in the process of manufacturing the cuff belt, joining the base fabric, attaching the male side zipper, attaching the ring, etc., if the base fabric is knitted with synthetic #A yarn, do not heat as described above. Although joining by means is preferable, each knitting yarn is synthetic N!
If it is not a-fiber, it may be bonded with an adhesive or sewn by sewing means.

The base fabric knitted according to the present invention has substantially the entire surface of the first area located on one side of the intermediate line formed into a loop portion having a loop-shaped engaged element, so that it can be used for arms or legs of any thickness. The cuff band can be fixed to the cuff band, and the wrapping is easy to adjust.Furthermore, since synthetic resin is attached to the back side of the base fabric, each engaged element can be securely fixed at that part. Even if the male side fastener and the male side fastener consisting of the group of engaged elements are repeatedly engaged and separated, the engaged elements will not stretch or come off.

According to the present invention, the base fabric formed in a rectangular shape is composed of a chain line, a tricot knit, a single cord knit, and a knitted structure, and the base fabric has a central portion in the width direction. Since it has a plurality of loop-shaped engaged elements formed by raising piles made of sinker loops of the single cord knitting on substantially the entire surface on one side of the intermediate line extending in the longitudinal direction, the loop-shaped cover is The engaging element is integrally formed with the base fabric,
Therefore, fold this base fabric along the middle line and
Even if it is made into a J-band, it does not thicken in that area and is convenient to handle.

In addition, since at least the part of the back surface of the base fabric opposite to the part forming the engaged element becomes a resin surface, the engaged element is stably maintained on the base fabric for a long period of time by the resin surface. Ru.

Furthermore, the base fabric can be easily woven with a knitting machine such as a normal tricot knitting machine, a double raschel knitting machine, a circular knitting machine, etc., and the pile raising, resin processing, etc. In addition, the process of separately manufacturing the base fabric and the hook-and-loop fastener as in the conventional method is no longer necessary, and therefore manufacturing costs and material costs can be kept low.
