Description

  The present invention relates to a curtain weight that is attached to a skirt of a curtain or a raised curtain to adjust the hanging shape of the curtain and prevent the skirt from rolling up.

  In curtains and raised curtains (hereinafter simply referred to as curtains), weights are sewn into the hems of the curtains for the purpose of adjusting the hanging shape when the curtains are suspended and preventing the hems from rolling up.

  The above weight is required to have an appropriate weight in order to achieve the above-mentioned purpose. In the case of a thick curtain having a heavy weight, a plate-like weight made of a metal such as zinc or stainless steel is used, and this is used for the hem. In the case of a thin and light curtain, weight chain is used to sew over the substantially entire length of the skirt of the curtain.

  A conventional weight chain is formed by using a number of weights formed in a short circular axis shape using a metal such as lead or stainless steel, and incorporating the weights alone into a small-diameter fiber cylinder knitted with yarn. The overall structure is flexible.

  By the way, since a needle is used to sew the curtain, it is necessary to check whether or not the needle is left behind by applying the stitched curtain to a meter-reading machine.

  If the weight chain sewn into the hem of the curtain has a metal part as before, when the curtain is put on the meter reading machine, the meter reading machine detects and reacts to the metal part of the weight chain, leaving the needle This will reduce the detection accuracy of forgetting.

  For this reason, the curtain sewing process employs a process in which a weight chain is attached to the curtain after the needle that has been left behind is checked with a meter-reading machine.

  However, the method of retrofitting the weight chain to the curtain has a problem that the sewing process of the curtain and the attachment process of the weight chain are separate processes, which requires extra labor and time for the production of the curtain.

  In addition, when lead is used to form the weight chain, there is a risk of causing environmental problems such as water pollution at the time of disposal.

  Accordingly, the object of the present invention is to prevent the weight from reacting to the meter reading machine, and the weight can be sewn simultaneously in the sewing process of the curtain, so that the efficiency of curtain production can be improved and the occurrence of environmental problems at the time of disposal is extremely low. In addition, since the degree of freedom in design is excellent, it is an object of the present invention to provide a curtain weight capable of producing a new product.

  In order to solve the problems as described above, the present invention attaches a number of weights formed using a nonmagnetic material to a flexible string body at predetermined intervals in the length direction of the string body. The configuration is adopted.

In another invention, a plurality of weights formed using a non-magnetic material are attached to a flexible string body at predetermined intervals, and these are attached to the inside of the flexible cylinder of the non-magnetic material. The built-in configuration is adopted.
The weight alone is formed in a shaft shape using a synthetic resin, and is attached to the string body so that the string body penetrates the center in the axial direction, or the string body is a synthetic resin string or fiber. It can be made into the structure which is formed with a string and this string body has a stretching property.

  Here, it is preferable to use a synthetic resin as a material for the weight alone from the viewpoint of meter reading and environment, but ceramic and non-magnetic metal can be used in addition to the synthetic resin, and each weight alone is attached to the string body. The interval may be set arbitrarily, but when the adjacent weight unit is folded into a parallel shape, the end of the adjacent weight unit will not collide and tension the string body. It is preferable to set the interval according to the diameter.

  According to the present invention, a large number of weights formed using a non-magnetic material are attached to a flexible string body at predetermined intervals, and this is incorporated into the flexible cylindrical body. Since the weight does not react to the curtain meter reading machine, the weight can be sewn at the same time in the curtain sewing process, and the efficiency of curtain production can be improved.

  In addition, since a large number of weights made of nonmagnetic material are attached to a string of flexible nonmagnetic material at predetermined intervals, the material used to form the weight and the size of the weight alone By selecting, it is possible to easily obtain the required weight, and it becomes easy to select and use appropriate weight weights for various weight curtains.

  Furthermore, if synthetic resin is used to form the weight alone, the design flexibility is excellent in terms of material, so it becomes possible to produce new products for complex shapes and sizes, etc. The occurrence of environmental problems at the time of disposal can be extremely reduced.

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

  In the first embodiment shown in FIGS. 1 and 2, the curtain A is attached to the suspension member 11 such as a curtain rail fixed to the building side by a runner 12, thereby opening the chamber in the opening portion of the building wall. The curtain A is arranged in a suspended manner, and a weight (weight chain) 13 is sewn on the hem a of the curtain A over substantially the entire length.

  As shown in FIG. 2, the weight 13 according to the first embodiment includes a string 14 in which a large number of single weights 15 formed using a non-magnetic material are formed on a long string 14 of a non-magnetic material having flexibility. Are attached at predetermined intervals in the length direction.

  Examples of the non-magnetic material used for forming the weight simple substance 15 include ceramic, non-magnetic metal, wood powder, glass, talc and the like in addition to the synthetic resin. The weight simple substance 15 is not only transparent but also colored. You can choose freely.

  Incidentally, examples of the synthetic resin used for forming the weight unit 15 include PBT, PET, polycarbonate, PP (polypropylene), and the like.

  Further, as the cord body 14, a non-stretchable string such as a fiber string that is a monofilament as shown in FIG. 2B and a synthetic resin filament string such as PET as shown in FIG. A certain string can be used, and in the case of the monofilament fiber string, the string can bend freely, so that the weight 13 can be formed along the smooth shape of the curtain. When attaching to the body 14 at the same time, any string that can withstand the molten temperature of the synthetic resin used to form the weight unit 15 may be used.

  The weight 15 is formed in a short circular axis shape using a mold, and is attached to the string body 14 so that the string body 14 penetrates the center portion in the axial direction. If each weight single unit 15 is attached to the string body 14 by providing a large diameter portion formed by knots or expansion by melting and embedding the weight single unit 15 in the position, The pull-out strength of the weight single body 15 with respect to the string body 14 can be improved.

  The method of forming the weight unit 15 with a synthetic resin is such that a groove for passing the string body 14 is formed on the overlapping surface of the upper and lower molds, and a plurality of weight unit molding parts are formed in the middle of the groove, In addition to feeding the string body 14 into the upper and lower molds, the resin is supplied to the molding part to mold the weight unit 15, and then the upper and lower molds are separated to release the weight unit 15 from the molding unit. Thereafter, the single weight is formed in the same manner as described above in a state where the string body 14 is fed into the mold and the upper and lower molds are overlapped.

  The weight of the weight unit 15 can be easily obtained by selecting the forming material and the size of the weight unit. For example, the weight unit 15 has a length L of 7 mm to 15 mm and a diameter. φ is molded to a size of about 4 mm to 8 mm, the interval W between the end faces of adjacent weights 15 is set to about 0.1 to 10 mm, and the weight of the weight 13 is set to 5 to 30 g per meter.

As a specific example of the weight 13, when PET is used for the weight unit 15, the weight unit 15 is formed with a diameter of 5.42 mm and a length of 10 mm, and the distance between adjacent end surfaces of the weight unit 15 is about 5 mm. If the weight 13 is manufactured by being fixed to the string body 14 at such an interval, the PET 13 has a specific gravity of 1.3 g / cm ² , so that a weight 13 weighing 20 g per meter can be obtained.

  The above-described interval between the individual weights 15 attached to the string body 14 is an example. When the string body 14 is non-stretchable, in order to prevent the string body 14 from being cut, the adjacent weight single bodies 15 are folded and arranged in parallel. It is preferable to set the distance according to the diameter of the weight single body 15 so that the ends of the adjacent weight single bodies 15 will not collide and tension the string body 14 when they are formed. If an elastic material having a stable yarn length is used for 14, it is possible to prevent the string body 14 from being cut without much consideration of the attachment interval of the individual weights 15.

  Next, the weight 13 a according to the second embodiment shown in FIG. 3 has a structure in which the weight 13 according to the first embodiment described above is incorporated into the flexible cylindrical body 16.

  The flexible tubular body 16 is formed of a small-diameter fiber tubular body knitted with non-magnetic yarn, and the entire weight 13a has a flexible structure, and the whole is a single weight chain. The appearance of the product can be improved.

  The curtain weights 13 and 13a of the present invention are configured as described above, and in the sewing process of the curtain A, the weights 13 or 13a described above are sewn over substantially the entire length in the folded portion corresponding to the hem a of the curtain A. In this case, sewing of the curtain A and sewing of the weight 13 or 13a can be performed in the same process, the process can be reduced, and when checking forgetting to leave the needle in the meter reading machine for the curtain A after sewing, Since the weight 13 or 13a, which is a non-magnetic material, is not detected, it is possible to accurately check whether the needle is left behind by the meter reading machine.

  Thus, the curtain A in which the weight 13 or 13a is sewn into the hem, as illustrated in FIG. Raises will be prevented.
