Definitions

  • the present invention relates to a guide-ring tape in which guide rings for guiding a pull cord of a curtain are aligned on a tape substrate; a curtain (such as a roman-shade-type curtain provided with a pull cord) provided with the guide-ring tape; and a structure for attaching the guide-ring tape to a curtain fabric, the structure being provided with the guide rings, which are a means for guiding the pull cord that acts as an opening and closing means of the curtain.
  • a roman-shade-type curtain is raised and opened by pulling a cord.
  • Snap fasteners equipped with guide rings are aligned on, e.g., the lateral edge parts of the curtain in order to allow the pull cord to move smoothly.
  • some of the snap fasteners equipped with guide rings are attached directly to the curtain, but since this operation requires labor, a so-called snap tape is also employed.
  • snap tape snap buttons are aligned at fixed intervals on a long tape.
  • a well-known example of the aforementioned snap tape is a tape in which rings are provided in contoured fashion at the required intervals to one side of a tape assembly, wherein the curtain-raising auxiliary tape is characterized in that mating parts for attaching the tape assembly to ring attachments are provided as molded plastic articles to the ring, the ring attachments on the tape assembly are made into plastic-molded female mating parts that correspond with male mating parts and are formed on the tape assembly by molding, and an engagement mechanism that can be forcibly disengaged is provided to the fitting surfaces of the two types of mating parts (see, e.g., Patent Document 1).
  • Patent Document 1 Japanese Utility Model Application Publication No. 63-27185
  • the invention according to Patent Document 1 is configured so that female snap fasteners made of a synthetic resin are arranged on a tape, and pull-cord guide rings are formed on male snap fasteners for engaging with the female snap fasteners, and this configuration continues to enjoy wide use.
  • the female snap fasteners are arranged on the tape, and all of the pull-cord guide rings engaged with the female snap fasteners must be unfastened from the female snap fasteners when the curtain fabric is to be cleaned or at other times.
  • the pull-cord guide rings removed from the female snap fasteners are prevented by pull-cord retainers from being separated from the pull cord, but the rings fall along the pull cord to the lowest end of the pull cord, and the pull-cord guide rings are gather together haphazardly.
  • the pull-cord guide rings gathered together at the lowest end of the pull cord must therefore be individually pulled up from the lowest end of the pull cord and then painstakingly attached to the female snap fasteners in order to reattach the male connectors of the pull-cord guide rings to the female snap fasteners attached to the curtain fabric.
  • the present invention provides a guide-ring tape characterized in that guide-ring units are formed by injection molding on tape through-holes aligned on a tape substrate, each of the guide-ring units being provided with a base and a guide ring that is integrated with a front surface of the base; and a basal through-hole is formed in the base.
  • a stepped coupler may be formed on at least a part of an inner wall surface of the basal through-hole.
  • the tape substrate may be a clear mesh material.

  • the present invention provides a structure for attaching a guide-ring tape to a curtain fabric, characterized in that a back-surface side of the tape substrate of a guide-ring tape in accordance with the first aspect of the present invention is a side contacting the curtain fabric; and the tape substrate is attached to the curtain fabric.
  • the present invention provides a structure for attaching a guide-ring tape to a curtain fabric, characterized in comprising a guide-ring tape in accordance with the first aspect of the present invention, and a snap tape in which snap buttons having male connectors for engaging with the basal through-holes of the guide-ring tape are aligned on a curtain-side tape substrate, wherein the snap tape is attached to the curtain fabric; and the basal through-holes of the guide-ring tape through which the pull cord passes are capable of engaging and disengaging with the male connectors of the snap tape, whereby the pull cord can be attached to and detached from the curtain fabric.
  • the present invention provides a structure for attaching a guide-ring tape to a curtain fabric, characterized in comprising a guide-ring tape in accordance with the first aspect of the present invention, and snap buttons having male connectors for engaging with the basal through-holes of the guide-ring tape, wherein the snap buttons are attached to the curtain fabric; and the basal through-holes of the guide-ring tape through which the pull cord passes are capable of engaging and disengaging with the male connectors of the snap buttons attached to the curtain fabric, whereby the pull cord can be attached to and detached from the curtain fabric.
  • a guide-ring tape characterized in that guide-ring units are formed by injection molding on tape through-holes aligned on a tape substrate, each of the guide-ring units being provided with a base and a guide ring that is integrated with a front surface of the base; and a basal through-hole is formed in the base, allowing the guide rings to be formed on the front side of the base extremely easily and inexpensively.
  • the guide-ring tape is attached directly to the curtain, whereby the curtain can be cleaned in a simple manner merely by pulling out the pull cord passed through the guide rings. Attaching the tape to the curtain is very convenient because the pull cord need only be passed through the guide-ring units without the units falling down.
  • the basal through-holes formed along with the formation of the guide rings can be made to function as female engagement holes of the snap buttons, and can be applied to the configuration disclosed in claim 6, 7, 9, or 10.
  • a stepped coupler formed on at least a part of an inner wall surface of the basal through-holes in the configuration according to the invention as cited in claim 1, whereby the part that interlocks with the corresponding male connector thereby acts as the stepped coupler when the basal through-holes function as female engagement holes, allowing a configuration to be obtained in which the tips of the male connectors do not protrude into the holes of the guide rings through which the pull cord passes, and allowing the pull cord to be inserted in a simple manner.
  • the pull cord and the tips of the male connectors do not rub against each other, and the durability of the pull cord is therefore not reduced by engagement with the male connectors.

  • the guide-ring tape according to Example 1 of the present invention has a configuration in which the guide-ring units 10a are aligned on a tape substrate 15a. More specifically, positioning holes 150, which are through holes, are formed at intervals of 10 cm on the long tape substrate 15a, which is composed of a mesh sheet of colorless, clear, heat-resistant synthetic fiber. Snap-molding dies (not shown) are fixed to the rims of the positioning holes on the front and back surfaces of the tape substrate 15a using six front and six rear fixing pins. The guide-ring units 10a are formed by injection molding in the snap-molding dies. In the process, the resin that forms the guide-ring units 10a is melted into the narrow openings of the mesh sheet of the tape substrate 15a formed from the heat-resistant synthetic fiber, and the guide-ring units 10a are formed tightly attached to the tape substrate 15a.

  • a configuration is adopted in which a plurality of the pull cords 2 are passed continuously through the guide rings 13 of the guide-ring units 10a, are led to guide rollers 4 positioned above the curtain 3 and through a hoisting lock mechanism (not shown), and are finally tied into a single cord. In this state, the other ends of the cords are attached to a pull tab 5.
  • the guide rings in Example 1 can be formed extremely easily and inexpensively on the front of the base by injection molding.
  • a curtain provided with the guide-ring tape 1a can be cleaned in a simple manner merely by untying the pull cord tied to the lowest guide-ring unit 10a, and pulling out the pull cord passed through the guide rings. Attaching the tape to the curtain is very convenient because the pull cord need only be passed through the guide-ring units without the units falling down.
  • a curtain according to Example 2 and a structure for attaching the guide-ring units 10a to a curtain fabric according to Example 2 of the present invention are configured using a curtain-side snap tape 1b, which is sewn to the curtain fabric 30, and the guide-ring tape 1a, which is not sewn to the curtain fabric 30 and to which the pull cord 2 is attached, as shown in FIGS. 8 through 10 .
  • the snap tape 1b has positioning holes formed at intervals of 10 cm in a long tape substrate 15b composed of a mesh sheet of colorless, clear, heat resistant fiber, as shown in FIGS. 14 through 16 .
  • Snap buttons 10b having male connectors are formed by the injection molding of the front and back surfaces of the rims of the positioning holes. The resin that forms the snap buttons 10b is therefore melted into the narrow openings in the mesh sheet of the tape substrate 15b formed from the heat-resistant synthetic fiber, and the snap buttons 10b are formed strongly attached to the tape substrates 15b.
  • the snap buttons 10b having male connectors are each provided with a male connector 14 in the center of a snap-button base 11b that has a width of about 10.5 mm, a depth of about 9 mm, and a thickness of about 3 mm, as shown in FIGS. 20 through 22 .

In this state, the other ends of the cords are attached to the pull tab 5.
  • the pull cord 2 is mounted on the curtain 3 when the connectors of the snap tape 1b and the guide-ring tape 1a are fastened together.
  • the configuration is such that the curtain 3 to which the tape substrates 15b of the snap tape 1b are sewn is removed from the pull cord 2 when the connectors of the snap tape 1b and the guide-ring tape 1a are unfastened from each other.
  • the guide-ring tape 1a used in Example 2 has the same configuration as the guide-ring tape according to the aforedescribed Example 1. Accordingly, each of the guide-ring units 10a of the guide-ring tape 1a is also the same as in Example 1, and the stepped coupler 120 is therefore formed at a position 1.05 mm from the bottom end of the base 11a on a part of the circumference of the inner wall of the basal through-hole 12.

  • the components of this structure are interlocked when the male connectors 14 are fit into the basal through-holes 12. Therefore, when the snap buttons 10b of the snap tape 1b and the snap-button bases 11a in the guide-ring units 10a of the guide-ring tape 1a are engaged, the top ends of the male connectors 14 of the snap buttons 10b are positioned on the same plane (i.e., are coplanar) with the top ends of the snap-button bases 11a of the guide-ring units 10a.
  • This configuration can prevent the male connectors from interfering with the pull cord passed through the guide-ring units 10a, and ensure that the function of the guide-ring units 10a to guide the pull cord 2 is performed smoothly.
  • the above-described configuration dispenses with the need to untie and remove the cord during when the curtain according to Example 2 is to be cleaned.
  • the curtain fabric 30 to which the snap tape 1b is sewn can be removed from the guide-ring tape 1a solely by separating the male connectors 14 of the snap buttons 10b and the basal through-holes 12 that function as female engagement holes of the guide-ring units 10a.
  • the guide-ring tape can be attached to the curtain fabric 30 by fastening the male connectors 14 of the snap buttons 10b aligned on the snap tape 1b, and the basal through-holes 12 of the guide-ring units 10a aligned on the guide-ring tape 1a.
  • the guide-ring units do not fall down along the pull cord, and can therefore be attached in a very simple manner.
  • a curtain according to Example 3 and a structure for attaching the guide-ring units 10a to the curtain fabric according to Example 3 are described below.
  • the attachment structure of the guide-ring units 10a according to Example 3 is the same as in Examples 1 and 2 as concerns the guide-ring tape 1a, which is the primary element of the configuration.
  • the snap tape 1b of Example 2 is not employed in she curtain according to Example 3 or the attachment structure of the guide-ring units 10a according to Example 3, as shown in FIG. 23 .
  • the snap buttons 10b are instead sewn directly to the curtain.
  • the snap buttons 10b have the same shape as do the snap buttons 10b of the snap tape 1b of Example 2.
  • the tape is not injection molded as in Example 2, and the snap buttons 10b that are used are molded in advance using well-known means.
  • the snap buttons 10b are directly attached to the curtain in this configuration, more time is needed to process the curtain during manufacture, but advantages are presented in that once the snap buttons 10b are attached to the curtain, the pull cord 2 need not be removed from the guide-ring units 10a when the curtain is to be cleaned, as in Example 2, and can be attached to the cleaned curtain in a very simple manner.
  • the present invention is not limited to the aforedescribed Examples 1 through 3 and, for example, the following can be freely set according to the size, thickness, pattern, or other characteristics of the curtain in question in the structure for attaching the guide-ring units 10a to the curtain 3 and in the snap tape used therein according to the present invention: the shape of the narrow part and the size of the snap buttons 10b and the guide-ring units 10a; the intervals of the snap buttons 10b and the guide-ring units 10a; the thickness, width, and length of the tape substrates 15a, 15b; and the like.
  • the snap tape 1b was attached to the curtain fabric 30 by sewing in the present examples, but the tape may also be attached using bonding, welding, or the like instead of sewing.
  • the tape substrates 15a, 15b of the present invention were colorless and clear in the examples, but may also be colored and clear.
  • a color tone that matches the color pattern of the curtain can be appropriately selected, whereby the tape substrates 15a, 15b can be made visually inconspicuous by the use of the clear mesh sheet having the same color as the color tone of the curtain and the color pattern of the curtain transmitted through the openings in the mesh sheet.
  • the shape of the basal through-holes and the shape of the male connectors are also not limited to the aforedescribed examples. Configurations are also possible in which, e.g., the basal through-holes lack the stepped coupler, the male connectors provided with the expanded-diameter head parts pass through the basal through-holes, and surface-side edge portions of the basal through-holes and the expanded-diameter head parts of the male connectors are engaged; and in which the elements can be detached from each other due to elastic deformation of the basal through-holes or male connectors.
