Ladies underwear, especially brassière

Technical field

The invention relates to a women's undergarment with elaborate shell, in particular a brassiere, containing the two bust cups side parts the front central area between the breast cups are connected to each other, which at the rear ends have a back fastener and with carrier tapes are provided.

State of the art

Bras are undergarments that in view to its intended cover, support and shape the female breast in many sizes and shapes must be produced and kept in stock. Through her, this provision matched spatial form conditioned, consist they conventionally composed of a plurality of different parts, to their composition of a variety of Operations require, which are time consuming and rewarding and a rational industrial operation largely unaffected. Besides the fact that a brassiere from a number of different parts, usually of textile Material, is, as side panels, bust cups, Carrier tapes, stocking or straight bindings, back closure etc., it is necessary according to a conventional manner, these Parts to be connected by sewing together. this requires not only at the connection points along withdrawing sewing operation, but also the use of a Connection medium, for example a suture.

There has been no lack of attempts in the prior art, one hand, this complex manufacturing process to simplify, but then look for a fit, the possible multiple sizes and shapes including, and Finally, these two conditions together to connect.

So is entitled "One for All" displaced bra known of each of two one-piece, the bust cups full side panels textile, stretchable material. These parts are in each case at the edges by strips of elastic reinforced material, obtained by spot welding with the Side parts are connected. In this manner there were also Carrier tapes produced, wherein at least this Reinforcement strips from the side parts, starting along the shoulder straps pass through. Although by this type of Edge reinforcements on the connection medium for the Sewing could be dispensed with, but still remains the Amount of time is required to the edges of the Brassiere to produce the weld joints to depart. Moreover, it was not for the connection Side panels, even for attaching the fastener parts or Carrier to dispense with seams.

Especially to the wearing comfort of such bra to increase, in which to increase the forming force Reinforcing members, such as rods, bars or the like are incorporated, it has also become known, Blanks in the form of to reinforcing areas of a correspondingly stronger material with a to conceal sealable polyester fabric and this Parts then made a second continuous workpiece together stretchable material and by heating to a three-layer workpiece to connect (US 5,154,659). After cooling, are then made of the elastic Basic material on the chest by the Molden Bust cups elaborated. Also, in this Bra, the side parts in the front Central axis by a sewing yarn with each other connected and the back fastener parts and shoulder straps sutured.

Similarly, it is for reinforcement of selected Areas of a garment such as a girdle or a brassiere, known on the basis of a textile material by screen printing in particular Patterns apply a powdered adhesive which then is melted in a drying oven (EP 0255101 B1). On the thus coated with adhesive areas based then one of the areas of the adhesive application applied appropriate topsheet of by application Heat and pressure by means of the adhesive with the basis is connected. are strength and forming properties here by the shape and size of the adhesive application and choice of Adhesive material determined. The other assembly also This bra is made by sewing.

Object of the invention

The invention is based on the object, a design a ladies' undergarment, in particular a to provide bra, industrial for a modern Manufacturing is suitable especially any consecutive and a connection medium requiring sewing avoids.

Summary of the Invention

According to the invention, this object is achieved by a Ladies' undergarment, in particular a brassiere achieved with the features specified in Claim first

Advantageous developments emerge from the Subclaims.

Compared with the conventional bonding techniques, in particular by sewing, the invention can Bra not only without any threads or similar Connecting means are produced, but it is also practically only sporadically, thus by pressing, welding or like, taking place operations for connecting the individual parts or for assembly required.

By eliminating most disturbing and the expansion behavior influencing or possibly brushing, by Sew seams produced, the new bras also improved wearability. Because of its flat Terminal edges or material transitions is the Bra invention ideal for wearing under fitting clothes because it is about on the worn clothing does not show. By decreased Material diversity arising easy to care for and also a simplified recyclability. After all allows the Production also better reproduction the required fit and a comparably favorable Cost structure in manufacturing.

In the drawing, the invention is an example of a Bra depicted as ladies undergarment. However, the invention is applicable to other garments applicable, which have a worked shell, such as eg swimsuits or the like.

In Fig. 1 is an inventive brassiere of the Inner side shown. The brassiere 1 is made two side parts 2 and 3, the mirror-symmetrical to a the front center axis M are formed and arranged. The Side parts 2 and 3 comprise in each case by Molden shaped breast cups 4 and 5. The side parts 2 and 3 are in the region of the front center axis M in a range 6 interconnected. At the rear ends of the Side parts 2 and 3 are the active and passive Parts of a back fastener 7 in the front upper region the side parts 2 and 3, above the bust cups 4 and 5, shoulder straps 8 9 are fixed and the rear Range at 10 in a by an adjustment 11 formed loop 12 adjustable fixed.

The side parts 2 and 3 each consist of a their entire surface covering layer 13 or 14 from a textile stretchable material to some degree, at least in part thermoplastically fusible fibers. On these base parts 13 and 14 are from the inside Reinforcing parts laminated, with in its entirety are designated 15 and the sixteenth These reinforcement parts 15, 16 also consist of a textile, preferably a less stretchable material, which is also at least in part thermoplastically fusible fibers.

As FIG. 1 shows, the reinforcing parts are made 15, 16 of frame-like blanks, the approximately uniform width, ribbon-like along the outer edges of the side parts 2 and 3 extend to here a reinforcement and stabilization of to effect edge. These are lower, parallel to the bottom 17 extending parts 18, located in the back area adjoining, extending to the support bands 8 Parts 19, along the upper edges 20 extending parts 21 and finally, above the bust cups 4, 5 extending Part 22. Starting from the bottom edge 17 of the brassiere 1 the parts extend 18 of the reinforcements 15, 16 to in the scope of the bust cups 4 and 5 into; they form there reinforcements 23 to support the breast or to Shaping its contours.

Although undergarment according to the invention here at Example of a bra with back closure and Carrier bands is shown, the invention is nevertheless not limited. The bra can be used instead also have a back closure a front closure or without closure as a so-called "step-in Bra" be formed. Similarly, he can even without shoulder straps, be so constructed strapless. Finally, the Invention on swimsuits, both one-piece and Bikini applicable.

To produce the brassiere according to the invention First, the two side parts 2 and 3 is produced, this then joined together in the front central area 6 and finally the carrier tapes 8 and the closure members 7 appropriate.

For the preparation of the side parts 2 and 3 of the brassiere 1 is first on a subway or a rough cut of the reinforcements 15, 16 forming the textile material a coating is applied, by which a connection with the subway can be 13 or 14 prepared. This can either a "hot melt" -Kleberbeschichtung, or a thin, activatable by application of heat film. Thereafter, in this rough cutting the inner contours of the Reinforcement members 15, 16 are punched and the remaining frame-like parts - still without outline - on the Rough blank for the blank portions 13 and 14 placed. By application of heat and pressure are the Reinforcement members 15, 16 containing coarse blanks with Coarse blanks 13, 14 of the base web connected. Only after the bust cups are 4 and 5 and the gemoldet Outer contours punched. It makes sense, two each corresponding side parts 2 and 3 in each other congruent position superimpose.

After these preparatory measures will start the Assembly of the brassiere. To this end, the one above the other and punched gemoldeten parts 2 and 3 pitched, the front central area 6 of Central axis M in a triangular overlap 23 brought and in this area by a weld 24 firmly interconnected. This can by a single Pressing and welding operation effected. This compound can by a design motif, as "bloom", optically be made attractive.

Then, the parts of the back fastener 7 and the Carrier tapes 8 attached. This may be reference to FIGS. 2 and 3 are explained, each larger cutouts show scale.

The fixed connection 9 of the shoulder straps 8 with the front upper portions of the brassiere 1, Fig. 2A. The Shoulder straps 8, which are mostly made of elastic band material consist, contain thermoplastic rule fusible fibers so that they, with the corresponding brought portions of the side parts 2, 3 in overlap can be joined together by welds 25th For adjustable mounting 10 of the shoulder straps 8 in the rear region (Fig. 2B) of the material of Side parts 2 and 3 with laminated reinforcing a Tab 26 is formed which is pulled through an eyelet 27 and then is repulsed. By a weld 25, the Tab 26 is welded to the side part 2 and 3 respectively. By Eyelet 27 is in a known manner, the carrier tape 8 drawn that a loop 12 forms.

is Similarly, with the parts of Back fastener 7 process (Fig. 3). The back closure 7 is 7a of an active closure member and a passive fastener part 7b. The active fastener part 7a has 7c a closure head, the passive fastener part 7b a recess 7d. set Both fastener parts 7a and 7b each in an eyelet 7e continued. Again, run the ends the side parts 2 and 3 of tabs 28 in each through the eyelets 7e and pulled backwards are handled, then by welds 29 to the Material of the side parts 2 and 3 are welded to be.

It follows that it for assembly of Brassiere invention none along a route running and a connection medium-requiring Sewing supplies; the production is limited to rather simple punching, pressing and welding operations, ie Operations, the automatic machines in a simple manner by Machines can run.

While the side parts 2, 3 of the invention Brassiere 1 in the FIG. 1 shown Embodiment in the front central area 6 by Overlapping 23 encountered and triangular by the Outline of the lap joint appropriate, also triangular weld 24 are connected, is also the possibility of the side parts 2, 3 in the front central Area 6 between the breast cups 4, 5 edges equal blunt to connect in a weld 30 to one another. This possibility is shown in Fig. 4A in detail in front view and in Fig. 4B in a corresponding cutout in a view shown from the inside. How such a blunt Weld can be produced in a simple manner, is schematically consecutive in some stages in the FIG. 5 to 7.

This simple connectivity based on the fact that According to the invention both for the rough blanks 13, 14 of the Side parts, as well as the reinforcement members 15, 16 Textile materials are used which at least in part thermoplastically fusible fibers. Such fibers can be prepared by application of ultrasound or Heat, optionally with the concomitant use of Pressure welded. It succeeds by Superposing the blanks from the coarse 13, 14 and the Reinforcement parts 15, 16 existing side parts 2, 3 in mutually congruent position these in the later front central area 6 forming ends 32, 33 by Welding with pressure application in full By separation so as to connect with each other, that after Serving the parts 2, 3, the two successive lying welded together ends 32, 33 in a stretched advised position and so edges equal dull together are welded. In this way can practically invisible, at least not Brushing straight Connection of the two front inner ends of the side parts 2; 3.

To secure this weld 30 and at the same time these very highly stressed front central area 6 of to strengthen the brassiere 1, it is useful, in this Area preferably on the inside of the brassiere Reinforcing member 31 aufzukaschieren which usefully from the same material as the side parts 2, 3 and even in the same manner as the different layers can be associated with these material layers (Fig. 4A / B).

How such a blunt weld 30 produced beneficial can be, FIGS. 5 to 7.

In Fig. 5 is illustrated schematically how the two Side parts 2, 3 from the base material 13, 14 and the Amplifying parts 15, 16 are superposed so that whose front inner ends 32, 33 overlap each other. Of the ply portion is then in the area of ​​influence brought an ultrasonic welder 34, the only by a sonotrode 34a and a bottom abutment 34b is indicated. The bottom abutment 34b has in its top, the material triangular facing portion Cross section to not only welding, but also to allow separation of the items.

By lowering guiding the sonotrode 34a in the direction of arrow 35 is the between the sonotrode 34a and the abutment 34b located material supplied energy. this leads to a heat development and thus welding of the Kunsttoffäden in the two layers of material. The two superimposed ends 32, 33 of the side parts 2, 3 connecting weld seam 30 is shown in Fig. 6, which the Situation after welding and separation is indicated.

Thus, the two front central edges 32, 33 of the Side parts 2, 3 joined together.

After breaking the two side parts 2 and 3 fall previously still superimposed ends 32, 33 in a extended position (Fig. 7), in which the side parts 2, 3 with their ends 32, 33 joined together edge-equal dull are.
