Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a toilet seat cover having a cylindrical structure that can be applied to an O-type or U-type toilet seat that is used while sitting. A part of the top cover has a core material insertion part on one end side for locking and holding on the bottom side of the toilet seat, and a locking part on the other end side for locking on the bottom side of the toilet seat by bypassing the top surface of the toilet seat. The present invention relates to a method of manufacturing a toilet seat cover provided with a stop.

Conventionally, when manufacturing a toilet seat cover with a cylindrical configuration, as shown in Fig. 1, a small diameter cylindrical body a knitted by a circular knitting automatic knitting machine is cut in the stitch direction at one point in the circumferential direction. After cutting the heddle t, both edges θ along the gauge direction
.

Alternatively, a large diameter cylindrical body a' is obtained after sewing bag parts A and C, and a core material is inserted into one side and rubber is inserted into the other. Therefore, many steps are required, such as cutting the small diameter cylindrical body a, sewing to form the large diameter cylindrical body a', and sewing the ends to form the core material insertion part and the locking part, which is extremely time-consuming. there were.

Therefore, in order to save the effort of forming the large-diameter cylindrical body a' from the above-mentioned small-diameter cylindrical body a, as shown in FIG.
A long material A knitted in advance into a large-diameter cylindrical shape is cut to an appropriate length in the direction of the axis of the cylinder to obtain a large-diameter cylindrical body a', and both ends of the sleeve in the direction of the core are folded back and sewn. It has been proposed to manufacture a toilet seat cover by forming the bag parts S and C, but this requires sewing to form a locking part such as the insertion part of the core material, which is time-consuming. In addition, when a long object A is delivered from a subcontractor and then manufactured into a product, the long object A expands and contracts under the influence of humidity, etc., and due to the difference in the cutting timing. There is an inconvenience that the length of the large diameter cylindrical body a' in the direction of the core of the sleeve changes, and as a result, the toilet seat cover as a product varies in size.

In view of the above points, it is an object of the present invention to provide a method for manufacturing a toilet seat cover having a cylindrical configuration at a low cost and with less labor by eliminating the need for sewing work for forming a core insertion portion and a locking portion. It is.

Embodiments of the present invention will be described below with reference to the drawings.

The toilet seat cover having a cylindrical structure obtained by the method of the present invention is
It is constructed as shown in FIG.

That is, a part 2 of the top cover 2 of the toilet seat has a plain or patterned pile knitted in a cylindrical shape with a circumference slightly larger than the inner circumference of the 0-type toilet seat 1.
A core material insertion part 3 formed into an annular shape by bag knitting is provided at one end in the direction of the sleeve core, and a C-shaped core material 4 is inserted therein, and both ends are connected by a joint member 5 to form a toilet seat l. The core material insertion part into which the core material 4 is inserted is formed into a circular shape that is larger than the inner circumference of the core material, and is provided with an elastic locking part 6 made of bag-knitted rubber thread on the other end side. 3 is locked and held on the lower surface of the toilet seat l, the locking part 6 is pulled upward through the opening lower of the toilet seat l, and the upper surface of the toilet seat l is bypassed,
By rotating and locking the toilet seat l from its outer periphery to the lower surface side, the portion where the buttocks touch the toilet seat l is attached to the toilet seat top cover part 2.
The sill cover is configured to cover the area. .

To manufacture the toilet seat cover, threads such as acrylic and cotton are used.
A circular knitting machine automatically knits bags to a predetermined length, then pile knits to a predetermined length, and then automatically knits bags to a predetermined length using rubber thread. The material insertion part 3, the toilet seat top cover part 2, and the locking part 6 are formed in this order,
Thereafter, a hole is made at an appropriate location in the core material insertion part 3, and the core material 4 is inserted through the hole to obtain the product. (See FIG. 4) Alternatively, bag knitting using rubber thread may be performed first, and the locking portion 6, the toilet seat top cover portion 2, and the core material insertion portion 3 may be knitted in this order.

The core material 4 may be made of plastic, piano wire, etc., as long as it has an elastic restoring force in the direction of diameter expansion, and various materials can be used. The material may be inserted through a stitch at the boundary between the bag stitch portion of the material insertion portion 3 and the pile stitch on the cover part 2 side.

In the above embodiment, by forming the locking part 6 by bag knitting using rubber thread, elasticity can be exhibited well over a long period of time, and the production can be made even easier by eliminating the trouble of inserting rubber. However, as shown in Figures 5 and 6, it is possible to knit a bag in the same way as the core insertion part 3 without using rubber thread, and then insert a round rubber 8 or a band rubber 9 there. You can also do it.

Incidentally, the toilet seat cover according to the method of the present invention can also be applied to a U-shaped toilet seat.

- At the end part in the knitting direction (for example, in the case shown in Fig. 5, when knitting in the order of core material insertion part 3 → force bar part 2 → locking part 6, part 6a in the figure), heat fusion is applied. After knitting the yarn, it is desirable to use bad air or hot water to bring the heat-fusible yarn into a fused state to prevent the knitting from coming undone.

Moreover, the core material insertion part 3 and the locking part 6 may be knitted with pile knitting or may be knitted without pile.

As explained above, in the method of the present invention, when a part of the toilet seat top cover is pile-knitted into a cylindrical shape, the beginning part and the end part of the part of the toilet seat top cover are folded to the part side of the toilet seat cover. With the cover turned over, a series of bags are knitted on one part of the cover, and one bag-knitted part is used as the insertion part for the core material that is held in place by the bottom leg of the toilet seat, and the other bag-knitted part is used to extend from the top surface of the toilet seat to the outer periphery of the toilet seat. Since the part of the toilet seat top cover, the core material insertion part, and the locking part are formed by a series of knitting in a single braiding process, There is no need for the conventional cutting process or sewing process for bag stitching, as well as the need for workers and sewing M machines.Furthermore, the product can be manufactured at the same time as knitting is completed, and all of the conventional drawbacks are eliminated. It has become possible to manufacture toilet seat covers at extremely low cost.
