Description

Adjustable closure device for bras and Similar and method for its production.

The present invention relates to devices of closing of utility in bras and articles of lingerie and corsetry and, in particular, refers to the so-called devices closure type clasp and clasp where an element of fastening arranged on a tie rod can be fixed on an element of coupling arranged on another strap, normally adjustable, for secure the garment, which may consist of a bra. The invention also relates to an improved method for the Production of the new closing device.

Although so far they have been provided, in many configurations, closing devices of the type used in bras, to ensure convenient and comfortable way between yes the two braces present on the back of the bra, normally adjustable, perhaps the most common is to use a configuration of the type of clasp and clasp. The male element of the closing device may consist of one or more brooches on one of the braces, while the female element is consisting of a plurality of square brackets separated from each other in a longitudinal direction to engage with the clasp so selective for an adjustable closure of the bra. The Square brackets can be metallic or powder coated. Be have encountered problems in previous constructions of this type with respect to the uniform die cutting of the product, since the tape is frequently provided with a lining or element of sewing coverage, and tapes, lining, threads used to join the coupling elements or to join the lining to the tape, etc., they are all elements that tend to die cut differently. The same can be said with regarding the coupling elements themselves. When the tape of the state of the art is sent to the device genre of closure and cut parallel to the longitudinal dimension of device by ultrasonic means, a pronounced edge is formed That is uncomfortable and annoying.

A known closing device and a method for its manufacture where some of the inconveniences arise mentioned above, are described, for example, in US Pat. 4,161,420.

In the field related to bras, corsetry and lingerie has been pursued for quite some time being able provide a closure device of the type used in bras that do not interfere with other garments, which are not damaged in the wash, that are comfortable for the user, that can be die cut evenly and preferably with them die cut characteristics that the garment and that are simple to buckle and unbutton, especially considering that the closure device is often provided on the back of the Username.

Therefore, the main purpose of this invention is to provide a closing device improved, especially for bras, but also suitable for closures of garments of other types, for example, for lingerie and corsetry, through which wishes are satisfied before indicated. Another object is to provide a method for closing device manufacturing.

In accordance with the present invention, said objects are achieved by the method of claim 1 and by the closure device of claim 15. The device for closure can be obtained by building a coupling half of the closure device with an inner tape or first tape of a knitted or knitted fabric (or a knitted fabric that has a cape knitted knitwear surface) consisting of a thread thermoplastic and joining said tape to a second tape in which the first tape is at least partially wrapped, by ultrasonic sewing along the longitudinal edges of the tape and providing the inner tape with its element of coupling through a molding operation so that, in the construction of this half of the closing device, it is not It requires no sewing operation.

The application of the coupling elements, which may consist of square brackets with holes formed in the first tape using ultrasonic die cutting techniques, and the assembly of the two tapes together, as well as the cutting of a length that forms half of the closing device from the continuous tapes that are used to produce the successive lengths, are all operations that can be performed by ultrasonic means, so that no sewing operation, except possibly to join the device of closing to the garment.

When all the tapes used are tapes knitted or knitted (or layers of knitted and knitted ribbons), by example, a polyamide (nylon) thread and the elements of Molded coupling are made of polyamide (by example, nylon), all the elements of the closing device they have substantially identical die cut characteristics and can be punched with the garment without being able to observe no important difference between the garment and the device closing.

The second tape in which the first tape covers the brackets with respect to the back and, of this mode, provides padding against the user's skin and, if if desired, another tape can be inserted, preferably also of knitted gender, between the second ribbon and the first, if so want.

According to a characteristic of the invention, the first and second tapes are sewn longitudinally in points separated from each other by ultrasonic welding, leaving wrapped skirts of the closure device below the which can enter a portion of the garment to join the closure device to the garment, for example, also by sewing ultrasonic or, as less preferable, by sewing.

The first tape can be perforated ultrasonic or mechanically to form a succession of holes and square brackets They can be molded onto the first tape around the holes. Of course, coupling elements can be used other than square brackets, although those are not preferable. The prisoners are also molded into the tape. These elements of coupling can be clasp type closure devices and bracket, for example.

The tapes can also be joined together by ultrasound along one end of the length formed by ultrasonic cutting of the lengths from the band.

The square brackets are preferably molded into the first tape in a succession of groups separated from each other from at minus three square brackets per group.

The male closure device may comprise a brooch molded on a ribbon made of thread thermoplastic, preferably a woven polyamide. In accordance with a feature of the invention, a succession of the clasps on the tape of the male closure device and the tape of the male closure device is cut by ultrasound between the clasps in the respective lengths of the closure device male that are secured to the garment, being the polyamide the brooches, the square brackets and the ribbons.

According to another aspect of the invention, the Coupling elements that apply to the gender tape are male and female elements that form a pressure button that can join by pressing the male element inside the element female.

According to one more feature of this aspect of the invention, the female element is open laterally through a constriction and the male element can slide transversely to engage with the female element and Connect the elements to each other. The separation can be done separating the male element from the female element in one direction opposite to that in which the male element was introduced.

When a row of male elements at one end of the brace and a row of female elements at the end of the other strap form the closure device on the back of the support, a high degree of flexibility is ensured as consequence of the separation of the male and female elements at along the respective row.

In an important aspect of the invention, the continuous tape that carries the elements may have inverted edges which are sewn by ultrasound except at points where inverted edges must be open at least one degree limited to introduce the respective braces, which they can then be sewn on the tape by ultrasound.

The tape is cut transversely and passes in the direction of the longitudinal edges so that, after the cut, rounded corners can be formed to protect the user against damage from pronounced edges in the corners

The closing devices of the invention are substantially thinner than metal tapes of the type clasp and clasp or snap type.

The clasp type closure device and square bracket can include:

a male half of the closure device injection moldable on a first tape and adapted to be secured to a part of a garment, being formed the male half of the closure device with a circular body generally flat that has an outer body portion in one from the sides of the first tape and an inner body portion on the other side of the first tape, a pin that projects in general centrally from the inner body portion, and a head formed in the pin; Y

a female half of the closure device injection moldable on a second tape and adapted to be secured in another part of a garment, the female half of the closure device with a circular body generally flat that has an outer body portion in one from the sides of the second tape and an inner body portion on the other side of the second tape, having the portion of time inside square bracket sized to receive and retain the head and an entry slot that leads to the bracket through which the pin can be inserted laterally, and the bracket head in a direction perpendicular to the tapes

According to the invention, the slot has a inward converging mouth and head, which may be heading for greater flexibility, it is tapered from a portion narrows to a thick portion in the direction of insertion of the pin in the bracket through the slot. Inner portion of the female half of the closure device may have flanks inclined that dock with the head and guide the latter inside the bracket.

As in the closing device of the state of the art and belonging to this requesting entity, it is highly advantageous to provide the body portion inside of one of the halves of the closure device as a convex element and the inner body portion of the other half of the closing device as a concave element that receives the convex inner body portion of the first half of the closing device in a fitting relationship.

According to another aspect of the invention, each one of the tapes may have a plurality of the respective halves of the closing device separated from each other in a row transverse to the referred direction of insertion and, to be able to adjust the closure device on the back, at least the tape provided with the female elements of the closing device can have a plurality of said rows longitudinally separated in the same.

The tapes can be covered each of they, at least on one side, with a gender strip brushed by ultrasonic welding to the tape along the edges and the part of the garment can be sewn or held by another mode between the respective tape and the brushed genre strips.

The ribbons can be woven based on a thread of synthetic resin and the halves of the closure device can be constituted by polyoxymethylene (POM) or polyamide (PA).

One of the advantages of the method of the invention is that the free ends of the belt / strip assembly to which the respective portions of the back closure device are connected, can be separated from the respective hands by cold cutting, so that they remain in a relatively soft state. Since they are not stiffened by a hot cutting tool, there is less chance of damage to the user resulting from the parts of the closing device. The halves, when joined together by the fastening movement, form a relatively thin flat closure without danger of applying pressure on the user's back. The thinness of the closure makes the brace of the bra back less likely to be shown through the wearer's outer garment. The parts of the closure device can be connected by a standard clasp and clasp movement to which the wearers of the support are accustomed, although the opening of the support can be facilitated because the parts of the closure can be separated by simply pulling the braces for separate them
each.

The above and other objects, characteristics and advantages will become more readily apparent from the following description, referring to the attached drawings, where:

Figure 64 shows the use of a film of flexible, soft and thin plastic material on which it Injection molds half of the closing device.

As can be seen from figures 1 and 2, The closure device of the present invention comprises a female half generally represented in 10 and that has a first Ribbon 11 of a knitted or woven polyamide (nylon) where they have have been drilled ultrasonically or mechanically elongated holes 12, which are shown here in a number of three and throughout whose margins have been molded by injection a bracket 13. The bracket 13 is made of the same polyamide that constitutes the thread from which tape 11 is manufactured. As can be seen from figure 10, the bracket 13 surrounds the edge 14 of the hole and continues above the flanks or faces 15 and 16 of the First tape The first tape 11 is, in turn, partially wrapped in a second tape 17, also of a knitted yarn of polyamide that has a pair of bent edge portions 18 and 19 above face 15 of first tape 11 and another portion 20 covering the reverse side 16 of the tape 11 (see figures 3-5).

In the region of bracket group 13, the folded portions 18 and 19 are ultrasonically welded to the face 15 of the first tape 11 and the first tape 11 is welded to the tape 17, the ultrasonic welding being represented in 21 by the clear lines shown there and by the arrows 22 visible in Figure 4, for example. Beyond welding seams Ultrasonic 21, the portions folded inwards 18 and 19 they form skirts as shown in figure 5 in which they can insert the edges of the garment so that, by other ultrasonic welding or by sewing, the strips shown in 10 in figures 1 and 2 can be fixed on the garment. The extreme of strip 10 is rounded at 23 and can be formed with another ultrasonically welded seam, as depicted in 24, for join the two tapes together.

As shown, comparing figures 1 and 2, the portion 20 covers the square brackets 13 on the back of the strip to provide a protective layer between said brackets and the User skin

The male strip 30 comprises a knitted tape 31 on which the coupling element 32 is molded, having the coupling element 32 (figures 6 and 7) a lip 33 which fits in bracket 13 below rod 34 thereof, while shoulder 35 can be adjusted under pressure against the rod 36 to retain the clasp in the bracket.

All described tapes can be constituted of the same polyamide of which the coupling elements 13 and 32, so that the entire device Closing features uniform die cutting characteristics.

As can be seen from Figure 8, the two coupling strips 10 and 30 can be connected to parts 37 and 38 of the garment, for example, by sewing in 39 or by ultrasonic welding, so that the two parts of the garment are they can hold together in the position shown in the Figure 8. From the back, the closing device it presents only the uniform region 20 in contact with the skin (compare figures 8 and 9).

You can get an additional padding against the user's back by another gender strip 40 knitted consisting of the same polyamide thread and inserted between the first tape 11 and the portion 20 of the second tape 17, as appreciate in figure 14.

The manufacturing mode can be seen in the Figure 11 where a band of the first tape 11 is fed to the along a path continuously and die cut ultrasonically to produce holes 12 in groups of three and the square brackets 13 are injection molded on the tape 11 around holes 12. Also, downstream along it run or on a separate run, the second tape 17 is partially wraps around the first tape, so that portions 18 and 19 reside on tape 11, and the 21 ultrasonic welding seams in separate positions between yes but in the regions of the bracket groups, and the band resulting from interconnected tapes can be cut ultrasonically at 41 to length 42 from the rest of the band 43 and form the transverse welds 23, constituting the lengths 42 the strips 10 described above. The phase represented in figure 13 is carried out downstream along the route represented in figure 12.

Male coupling strips are made of similar way in a manufacturing line and the lengths of the two strips are applied to the garments as already described previously.

Figures 15-21 show a pressure button connector that can be provided on the respective tapes that carry the male and female elements, being formed the female element as a bracket according to the principles described above.

As can be seen from the figures 15-17, the male element 50 of the pressure button it has a head 51 formed with a groove 52 in which it is received the tape and a convex surface 53 that is formed with a depression 54. On the opposite side of this head, it is planned a projection 55 surrounded by a concave portion or recess 56 whose curvature coincides with the convex curvature of the female element that It is described in connection with Figures 18-20. How can be seen from figures 16 and 17, projection 55 has a shaft 57 that is divided into 58 and formed with protrusions 59 in its ends and depressions or circular holes 60, separated equally angularly around the head, allow molding more securely the closure element on the tape.

As can be seen from the figures 18-20, the female element 61 has a disk shape and it is formed with a groove 62 in which the tape is received and it has a hole 63 provided with a constriction 64 along the  which projection 55 can be pressed, so that the projections 59 reside on the side of the constriction opposite to that on which the head of the male element is located (see figure 21).

To facilitate the insertion and separation of the projection, hole 63 has converging flanks and conical divergent 65 and 66 on opposite sides of the constriction 64.

The curvature of the concave portion 67 of the female element 61 coincides with the curvature of the concavity 56, of so that the total thickness of the assembled pressure button (figure 21) is comparatively small and substantially less than 5 mm

The male element 50 is shown arranged in the tape 68 in figure 21, while female element 61 is arranged on tape 69 and the back of the device closure is also covered by a strip of brushed gender in 70 to pad the closure device with respect to the body of the Username.

While the pressure button in the figures 15-21 is coupled by pressing the male element in the female element and is released by separating the elements from each other, it you can use the same principle with a side coupling of the male element in the female element. In that case, the male element of closing device can be the one described in connection with the Figures 15-17, while the female element 71, as shown in figure 22, it has a side mouth 72 connected to hole 73 through a constriction 74 past which the projection of the male element can be pressed. The element Female is formed on tape 75 in this mode. Alternatively, the female element 76 may be elongated and be provided with constriction 77 passed which can force the projection, a funnel-shaped guide 78 is provided for guide the projection inside the female element. How can seen from figure 28, the female element may be tapered, so that the projection can be guided by the touch inside the hole, since the user can easily discern the direction of insertion as a result of greater thickness in that direction.

Other configuration of the female element is shown in 79 in figure 27 and works with the same principle as that of the female element 76 of figures 23 and 28.

It will be noted that normally a number of said female elements in a row transversely with with respect to the tape (figures 29-31) of a bra closure device. However it is possible provide a single closure device 80 on the tape 81 in each position longitudinally with respect to the tape and, in that case, the closing device can be lengthened but, on the other side, it works according to the principles described, allowing that the male element 82 (figure 25) with its projections 83 is coupling behind constriction 84 by laterally inserting the male element in the female element. The male and female elements can be separated from each other in the same way as the button pressure, in the manner described above.

From figures 29-31 it will be apparent that rows 84 of the elements can be provided female 71 on tape 75 which may have rolled edges 85 provided with welded seams 86 that keep in place said rolled edges. Welding seams are interrupted in 87 between groups of rows 84 and where the tape is cut to secure each segment of tape with three rows, by example, on the respective strap of the back of the bra 88 (figure 30). For that purpose, once tape 75 has been cut in a region between groups of rows, the border is opened lacking seam 87 to receive a tongue of shoulder strap 88 and then it closes on said strap, after which they are provided welding seams 89 to secure the tape to the tie rod of the support. Simultaneously, a similar layer can be applied to the shown at 70 to pad the strap where it enters contact with the user's back.

Similarly, the row of male elements 50 on the tape 68 can be attached to the brace 90 of the bra so that, by lateral insertion, the male elements 50 can be insert into the female elements of one or the other row 84 (see figure 31).

When tapes 75, 68 are cut transversely between the rows of male or female elements or groups of such rows, the free corners can be rounded as shown in 91 and 92 in figure 30, to prevent damage to user by the presence of pronounced corners. In this way, no only the edges of the tapes are rounded by virtue of their lamination on the edges 85, but the corners are rounded to prevent damage or clogging of garments.

As can be seen from Figure 32, a plurality of female halves 110 of the closure device can be injection molding on a woven web 111 of resin threads thermoplastic synthetic that is covered, on one side, by a strip of knitted gender, as will be described with greater detail in relation to figures 52-55, said strip folding over the inner side of the tape in 112 and being welded with a pair of welding seams Longitudinal Each of the female halves 110 of the device closure (see figure 33) has an inner part 113 and a outer part 114 visible on opposite sides of the tape (no shown in Figures 33-35), the outer part or body 13 with a bracket 115 into which it ends a slot 116 from the periphery of the inner part, having said groove a mouth 117 that converges inwards.

Both the inside and outside can have through holes 18 that facilitate fastening on the belt of the injection molded body.

From the outer side, the bracket appears as a hole 19 in the center of the injection molded body that It can be composed of polyoxymethylene or polyamide.

The male half 120 of the closure device (figure 36) can be injection molded on a woven tape 121 which, similarly, may be covered, on its side outside, by a strip of knitted gender, folded in 122 and welded to the tape by ultrasound. The male half of the closure device may have an inner body portion 123 formed with a strut or pin 124 and a head 125 that is provided with a slit 126. The outer body portion is shown in 127 in figure 38 and may have a hole 128 in its center aligned with the strut. Head 125 conifies from a narrow end 129 to a thick end 130 (figure 39) in the insertion address in the respective bracket.

From figure 41 it will be clear that the inner body portion 113 of the female half 110 of the closure device, injection molded on tape 111 as shown in figure 41, it is convex and is received in the concave inner body portion 123 of the male half 120 of the injection molded closure device on its belt 121.

From figures 41 and 42 it will also result evident that the thicker portion 130 of the head 125 of the pin 124 resides near the bracket and is guided to its position by inclined surfaces 131 of the female half 110 of the device closing (figure 42). The female half of the closure device is shows in greater detail in figures 43-47 and it has a flange 132 that surrounds the bracket and below which the thin portion 129 of the head falls when the latter is Insert in the bracket in the direction A (figure 44). Because the head is divided and can be compressed together, the male half of the closure device can be removed from the middle female of the closing device in a direction perpendicular to the tapes

In Figures 48-51, it is shown in greater detail the slit 126 of the male half 120 of the closing device In addition, in figure 51 it is shown with greater detail the concavity 132 of the inner body portion of the male head of the closing device.

As will be evident from the figures 52-55, the female halves 110 of the device closure can be provided in a succession of rows on the 111 tape that is covered by the knitted gender strip brushed 133 shown in figure 54, so that the edges folds 112 can be fastened on the tape 111 by seams by ultrasonic welding 134 which may have a design of sewing stitches The free end of the resulting band can be cold cut at 135 to leave a soft spongy edge, while the opposite end may be open for introduction of part 136 of the bra back strap, which can then be sewn in place along the seam 137. Similarly, the shoulder portion 138 for the the back of the bra can be inserted between the tape 131 of the male halves 120 of the closure device and the gender strip knitted brushed 139 and sewn in place by stitches of sewn 140.

In Figure 55, the knitted gender strip brushed 139 and woven synthetic resin tape 121 are shown in more detail in section.

From figures 56-58, it will be clear that the halves of the closing device and, for example, the female half 150 of the closure device, can present annular configurations other than the circular. By example, in figures 56-58 half of the Closing device is shown with oval configuration and formed with body portions 151 and 152 injection molded on opposite sides of the woven support of the closure device (Figures 61-63) or on a flexible film, soft and thin 153 that can be transparent, as shown in Figure 64. Convergent mouth 153 leads here to the opening central 154 which has a part 155 adapted to protrude from the head of the male element as described above. In any of the modalities, the female element 155, for example, can be provided with a wedge-shaped projection 156 opposite mouth 153 and positioned to engage in groove 157 formed in head 158, when the male half 159 of the device closure is locked in the female half of the device closure, as shown in figure 60, thereby causing the wedge 156 effect a cam movement on the two parts of the head to separate them and increase the resistance with which the male half of the closing device returns to the female half of the closing device

Figures 61-63 show the tape padding and, although illustrated with respect to a female half 160 of the closure device, the same applies to both male and female halves of the closure device.

The tape 161 (figure 61) comprises the support fabric 162 of the closure device on which they are molded by injection, as described above, halves 160, etc. of the closing device The knitted outer strip 163 has edges outstanding 164 that are ultrasonically welded to the support fabric 162 of the closure device and, between these two strips, is find a padding strip that has been represented in 165 and that it can be a knitted tape, a non-woven strip or even a foam material.

The edge of the tape can be cold cut transversely at 166 and the surface of the cover strip knitted back towards the user's body can be brushed at 167 to provide a particularly soft touch or soft.
