Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a toilet seat cover that is attached to a U-shaped toilet seat.

[Prior art]

Generally, this type of toilet seat cover is made by sewing and sealing both ends of a knitted stretchable cylindrical fabric, and by forming a notch of the required length on the peripheral wall of the middle part, and forming a notch of the required length on the peripheral wall of the notch. Widely used are those in which openings are formed by sewing elastic material along the sides. However, such a toilet seat cover requires many sewing steps, and also involves many manual operations such as making cuts to form the opening and sewing elastic material to the opening.

For this reason, in recent years, a toilet seat cover as shown in FIG. 7 has been proposed (Utility Model Application No. 111300/1983).
This toilet seat cover is made by, for example, knitting approximately 10 courses of flat knitting with the short fiber yarn on the front side and the long fiber yarn on the back side, knitting a linking line of 34L, then switching to pile knitting, reducing this, knitting, widening. The tip part 31 is knitted into a curved surface by so-called toe knitting, and then the cover main body 30 is knitted by bag knitting with pile knitting,
When the length is about 40cm, knit the next 20cm or so to form the cutting line. This cutting line becomes an opening 36 for attachment and detachment. After forming the cutting lines, bag knit again to knit the cover main body 30 to about 40 cm, then reduce stitches, widen stitches,
The right end 32 in FIG. 1 is knitted by so-called toe knitting, and about 10 courses of linking line 34r are knitted by flat knitting. After this knitting is completed, the linking lines 34l, 34r and the cover main body 30 are sewn together using an overlock sewing machine, and the cutting line formed at the center of the cover main body 30 is cut with scissors or the like to form an opening 36. . This opening 36 is for attachment and detachment from the toilet seat, and an annular elastic body 35 such as a wide rubber band is applied to the inner end.
The elastic body 35 is wrapped around the opening edge with a decorative thread using a clam sewing machine like a buttonhole.

[Problem that the invention attempts to solve]

However, in the conventional method as described above, it is necessary to form the linking lines 34l and 34r at both ends, to sew the opening 36 with an overlock sewing machine, and to cut along the cutting line, which poses problems in terms of manufacturing efficiency. , and the opening 3 due to the structure.
6 is weak and easily breaks, and its cylindrical shape makes it difficult to conform to the shape of the toilet seat, especially the roundness of the base end.

The present invention was developed in view of the above circumstances, and its purpose is to strengthen the structure of the opening that easily causes damage and breakage when attaching to and detaching from the toilet seat, and to make it possible to use the toilet seat over many years. To provide a toilet seat cover that conforms to the shape of a toilet seat without causing any hindrance, and can prevent the cover from falling off the toilet seat even after it is covered.

[Means for solving problems]

The present invention is a cover for a U-shaped toilet seat that is inserted into the toilet seat through the opening ring, and the legs of the toilet seat are inserted into the two legs. a pair of legs having a predetermined distance therebetween and having inner edges thereof forming a U-shape;
One end side is knitted at the middle part in the width direction when folded, and the remaining part is a ring part knitted in series with the peripheral wall of each of the legs, and the entire circumference of the other end side of the ring part. An open ring part is knitted using a combination of rubber thread and ground thread, and a series of heat-shrinkable threads are knitted around the entire circumference of the opening edge of the open ring part, and this thread is further heat-shrinkable. It is characterized by having a reinforced edge.

[Effect]

The toilet seat cover of the present invention is inserted into the toilet seat through the opening ring, and after inserting both legs of the toilet seat into the legs of the cover, the opening ring is moved to the toilet seat pivot and attached to the toilet seat. The cover is held on the toilet seat by the contraction force of the opening ring, and the inner edges of the U-shaped legs fit into the inner periphery of the toilet seat.

〔Example〕

The present invention will be specifically explained below based on drawings showing embodiments thereof. FIG. 1 is a schematic diagram of the toilet seat cover according to the present invention (hereinafter referred to as the present product).
3 is an annular portion, 4 is an elastic ring portion, and 5 is a reinforcing edge portion. The legs 1 and 2 are spaced apart from each other by a required distance, and are connected to the legs 1 of the toilet seat 10, respectively.
In accordance with the size and shape of the legs 1l and 11r, the inner edges of both legs 1 and 2 are formed into an inverted U-shaped cylinder, and the tips are knitted with a slightly rounded shape.
Further, the base end is knitted in a series so that its entire circumference is connected to the annular portion 3. Subsequently to this annular part 3, an elastic ring part 4 having greater elasticity than this annular part 3 is knitted, and furthermore, a reinforcing edge part 5 is knitted around the entire circumference of the mouth edge of this elastic ring part 4. be.

Next, the toilet seat cover as described above is made on a flat flat knitting machine.
For example, an example of the procedure for knitting on a parallel and horizontal machine will be explained based on FIGS. 2 and 3.

FIGS. 2A to 2C are explanatory views showing the manufacturing process of the product, and FIGS. 3A to 3D are explanatory views showing the knitting mode. First, as shown in Figure 2A and Figure 3A, knitting begins with the latch needles on the front needle bed F and rear needle bed B of the horizontal machine.
Using Nf and Nb, latch needle Nf of front needle bed F, rear needle bed B
Rubber knitting portions 1a and 2a are knitted to have a length equal to the length of the arcuate portions at the lower ends of legs 1 and 2 by so-called rubber knitting in which yarn a is passed alternately like a latch needle Nb.

Next, as shown in Fig. 3B, in the return trip after rubber knitting, knitting is performed from the right side (or left side) to the left side (or right side) using only the latch needle Nb of the rear needle bed B, and in the subsequent outbound trip, the front needle is knitted using only the latch needle Nb of the rear needle bed B. Using only the latch needles Nf on floor F, knit from the left side (or right side) to the right side (or right side) and repeat this in order to make bag knitting, but during this time, increase the required number of stitches on each outbound and return trip. The tips of the legs 1 and 2 are knitted in a shape that follows the tip of the toilet seat.

The ratio of the widening stitches may be set depending on the shape of the tips of the legs 1 and 2 to be knitted.

When the number of stitches corresponds to the width dimension of the legs 1 and 2, as shown in FIG. Or do bag jiya guard knitting.

When the legs 1 and 2 have been knitted to the required length, as shown in Fig. 2C, the required number of additions is repeated on the inside of both legs 1 and 2 on the outward and return journeys, respectively, to form the toilet seat. It is formed into an inverted U-shaped arc that matches the inverted U-shaped inner circumference. By carefully setting the number of widening lines, it is also possible to form a gentle arc shape that is equivalent to the U-shape of the inner periphery of the base end of the toilet seat, as shown in FIG. Furthermore, the second
The latch needles Nf and Nb of the front needle bed F and the rear needle bed B are used between the inner edges 1i and 2i of the legs 1 and 2 in the parallel knitted state as shown in Figure C. After doing one course of rubber knitting similar to that shown in Fig. 3A and tying both legs 1 and 2, the legs 1 and 2 are tied together.
Similarly, the annular portion 3 is knitted by bag knitting or bag jia guard knitting. This bag knitting or bag jiya guard knitting consists of both legs 1 and 2 knitted in parallel.
This is done over the range connecting the outer edges 1o and 2o in the pressed and folded state. After knitting the annular portion 3 in the required course, the elastic annular portion 4 is then knitted using base yarn and rubber thread all around the annular portion 3.
form.

In knitting the elastic ring part 4 by bag knitting, as shown in FIG. 1 for every two latch needles Nf and Nb of B
The so-called 1×2 knitting is carried out on the needles of a book. Of course, the number of stitches of the rubber thread b may be two or more.

In addition, each of the leg parts 1 and 2, the annular part 3, and the elastic ring part 4
It goes without saying that the knitting method is not limited to the above-described embodiments, and that various conventionally known knitting methods may be adopted as appropriate.

When the knitting of the elastic ring part 4 is completed, the reinforcing edge part 5 is then knitted over the entire circumference of the elastic ring part 4 using heat-shrinkable synthetic fiber yarn d for several courses. Form. When knitting is completed, the process moves to a molding step, where the reinforcing edge 5 is heat-treated with steam to shrink the heat-shrinkable yarn d. For this heat treatment, a conventionally known method may be adopted, such as immersing the reinforcing edge portion 5 in hot water at a predetermined temperature or blowing hot air onto it.

As a result, the thread d contracts to form a small loop, reinforcing the periphery of the elastic ring 4, and has elasticity that is slightly smaller than that of rubber thread but stronger than that of rubber thread. This serves to prevent the knitted part of the opening from fraying. Usually, a toilet seat is formed in a U-shape close to an oval, with the middle part curved outward, so the opening edge of the cover that covers it has elasticity that allows it to pass through the outward curved part, Once attached to the toilet seat, it is necessary to provide a necessary restraining force near the pivot portion of the toilet seat so that it does not easily slip out of the toilet seat. However, in the case of ordinary rubber, etc., its elasticity easily deteriorates, and when it deteriorates, the binding force is weak and there is a risk of it falling out of the toilet seat during use. It has a large contractile force as it shrinks, and also has excellent stretching force, which strengthens its ability to prevent it from slipping out of the toilet seat.

In addition, the elastic ring part 4 makes it easy to attach and detach the cover to the toilet seat due to its large elasticity, and when it is attached to the toilet seat, it applies an appropriate tensile force to the cover to prevent wrinkles. Prevents it from bunching up and maintains a beautiful and clean appearance.

The product as described above is inserted into both legs 11l and 11r of the toilet seat 10 from the opening edge as shown in FIG. 4, and each leg 11l and 11r is inserted into the legs 1 and 2 as shown in FIG. The portion 4 may be moved to the vicinity of the pivot portion of the toilet seat 10.

The elastic ring part 4 and the reinforcing edge part 5 contract due to their strong elasticity, tightly restrain and hold the toilet seat 10 in the vicinity of the pivot part, and prevent it from slipping out, and are formed in an inverted U shape. The shape between the legs conforms to the shape of the toilet seat to prevent wrinkles.

〔effect〕

As described above, in the present invention, both legs are knitted parallel to each other with a predetermined interval, so when the legs are placed over the legs of a U-shaped toilet seat, the base ends of the legs are torn even if the legs are opened wide. There is no risk of it breaking or breaking, and although it has different knitting parts, it can be knitted in series on one knitting machine, so almost no manpower is required, resulting in significant labor savings. The heat-shrinkable thread is heat-treated to form a reinforced edge with strong elasticity, so it has greater strength than rubber cord, and the opening edge of the cover is strengthened, making it easy to attach and detach from the toilet seat. This also prevents the opening edge of the cover from breaking, damaging, or fraying, preventing it from slipping off the toilet seat, and by forming the U-shape between the legs of the cover, it reliably prevents the cover from sagging. Ideas are highly effective.
