Description

DEVICE FOR ADJUSTING THE DISTANCE BETWEEN THE CAPS OF SUPPORT-

THROAT

  The present invention relates to the general technical field of lingerie accessories, intended to adjust the undergarments to the body of the user.

  The present invention relates to a device for adjusting the distance between the cups of a bra that can be manipulated by the user, so as to adapt the spacing between the cups according to the measurements of the user and the desired comfort .

  The present invention more particularly relates to a device for adjusting the distance between the cups of a bra, comprising at least one flexible cord intended to be associated with the side edges vis-à-vis the two cups, so forming two attachment strands, and also comprising a length adjusting member of the attachment strands, wherein said strands are slidable against an elastic locking member.

  Such a device must necessarily be small, so as not to provide discomfort to the user. However, the smaller such a device, the more difficult it is to handle, which can induce a setting both long and insufficiently close the distance between the cups.

  The present invention also relates to a method of adjusting such a device comprising a step of compressing actuating means during which the length of the strands can be adjusted, and a step of releasing the pressure on the actuating means ensuring blocking the cord.

  The present invention finally relates to a locking cord of a device for adjusting the distance between the cups of a soutiengorge.

  It is known from EP-1 146 251 to provide a device for adjusting the spacing between the cups of a brassiere, comprising an assembly of three parts pre-fixed to each other in which two slides pass and can slide cords.

  Blocking of said cords is achieved by obstruction of the passage duct cords by means of a rod, provided at one of its ends with a protrusion, and at the other end of a head on which the The user exerts a pull to effect the locking of the cord by compression and friction at the level of the protuberance.

  Deblocking is achieved by pressing the head of the rod, which has the effect of substantially releasing the conduit and eliminating the radial pressure exerted on the cord. The user is then able to pull the cord strands released, upstream or downstream of the device, so as to slide them and adjust the distance between the cups.

  However, such a device assumes a method of pre-assembly and pre-assembly of the parts, before use, which is relatively complex and irreversible, so that it is very difficult, if the cord escapes from one of the ducts. of the adjustment device, reinsert it.

  In particular, it is not possible for the user to remove, for example when she wants to wash the bra, the adjustment device and then put it back in place itself.

  On the other hand, the manipulation of the locking / unlocking means of the! 1Peripheral Petrificial i ndiscriminating the nt of the in fl uction and reci nition rcess to maneuver.

  Thus, during adjustment, a finger (eg the index finger) of the user must press the locking rod to release the cord, but the maintenance of the adjustment device by the user assumes the partial obstruction of the conduit 10 output of the cord by another finger (for example the thumb) thus opposing the sliding of the latter. The gesture adjustment is therefore inconvenient.

  On the other hand, the adjustment requires exerting a considerable pulling force on the cord, so that the adjustment is made in batches and it is difficult to finely adjust the distance between the cups.

  Moreover, following repeated manipulations, the cords invariably end up wearing due to the friction exerted on the locking means. The wear can be first superficial, conferring on the cord an unsightly appearance, then worsen until it leads to breakage of the cord.

  Another disadvantage of such a device comes from the need to perfectly control the diameter of the cord, which is very difficult to achieve technically. Thus, if the cord diameter is too small, it will tend to be imperfectly blocked and it will not allow for reliable and durable adjustment of the distance between the cups. Conversely, if the diameter of the cord is too large, the user will have the greatest difficulty in unblocking and sliding, which can affect the ease of adjustment of the distance between the cups, the adjustment being made with fits and starts.

  Finally, since the device is irremovable, it must be washed in the same way and as frequently as the brassiere, which may lead to wear or damage to the constituent materials (metal or rigid plastic, etc.). washing machine washes are frequently repeated.

  The objects assigned to the invention therefore aim to remedy the disadvantages of the devices of the prior art mentioned above, and to propose a new device for adjusting the distance between the cups of a bra having ease of both grip and handling significantly improved over previous devices.

  Another object of the invention is to provide a new device particularly simple in its assembly, assembly and operation, while ensuring excellent blocking.

  Another object of the invention is to provide a new device that can be maintained mounted with a reduced number of parts.

  Another object of the invention is to propose a new device that allows secure locking of the cord.

  Another object of the invention is to provide a new device that is removable, so as to prevent its wear during, for example, washing the bra.

  Another object of the invention is to propose a new device allowing a fast, reliable and fine adjustment of the distance between the bra cups, and which allows easy sliding of the cord.

  Another object of the invention is to propose a new device that is robust.

  Another object of the invention is to provide a method for quick and reliable adjustment of a device for adjusting the distance between the cups of a bra.

  Another object of the invention is to propose a locking cord of a device 10 for adjusting the distance between the cups of a bra.

  - Figure 6 illustrates, in a sectional side view, the adjusting member in the compressed position (a) and in the rest position (b), in which the cord slides.

  According to the invention, and as shown in Figure 1, the device for adjusting the distance between the cups of a brassiere comprises a flexible cord 1, intended to be associated at two attachment points 2a, 2b with the side edges 3a, 3b facing the cups 4a, 4b of the bra, so as to form two attachment strands 5a, 5b.

  It is conceivable, as an alternative and without departing from the scope of the invention, to split this cord 1 into two half-cords intended to be fixed by sewing, welding, or any other means well known to those skilled in the art, at the two attachment points 2a, 2b located on the side edges 3a, 3b vis-à-vis the cups 4a, 4b of the brassiere.

  The cord 1, respectively the two half-cords are made from textile fibers, metals or plastic material.

  In the following, all references made to the cord should be understood as also applying to the half-cords, these two variants being equivalent.

  According to the invention. the device also comprises a regulane oroane 6 of the length of the attachment strands 5a, 5b, in which said strands can slide against a locking member 7.

  According to the invention, and as illustrated in FIGS. 2 to 6, the locking member 7 is formed of at least one pair of parts 7a, 7b intended to come into contact with said strands 5a, 5b via wedging means 8a, 8b.

  According to the invention, the two parts 7a, 7b are preferably mounted in opposition and movable relative to each other, and also comprise means for actuating the adjusting member and wedging means 8a , 8b mounted opposite each other.

  According to the invention, and as shown in Figures 1 to 6, the actuating means are provided on the two parts 7a, 7b so as to each have a substantially flat outer surface. Mounted opposite each other, they are intended to be pressed against each other by the user.

  According to the embodiment shown in Figure 2, the actuating means are formed by the ends 9a, 9b of the two parts 7a, 7b forming the adjusting member 6 in the form of clamp.

  The wedging means 8a, 8b are formed at each end of the two parts 7a, 7b, on the internal faces facing them, and are for example formed by the longitudinal edge of the ends of the clamp opposite the means actuating means 9a, 9b.

  Advantageously, the wedging means 8a, 8b can each have an external surface provided with roughnesses or teeth, the two surfaces thus formed being conjugate, so as to facilitate the locking of the cord 1.

  The locking member according to the invention, as shown in FIGS. 2 to 6, also comprises at least one compressible elastic element 10 interposed between the actuating means 9a, 9b.

  This compressible elastic element 10 is preferably mounted in the locking member, so as to be oriented perpendicularly to the plane formed by the two strands 5a, 5b passing through said member. Thus, each of the ends 10a, 10b of said elastic element bears against one of the internal faces of the parts 7a, 7b.

  This orientation of the elastic element 10, which is also preferably mounted perpendicular to the actuating means 9a, 9b, facilitates the manipulation of the adjustment member 6.

  According to the embodiment shown in FIG. 2, the elastic element 10 is fixed, by its ends 1 Oa, 1 Ob, to each of the parts 7a, 7b, so that it forms a permanent connecting element between the two pieces 7a, 7b.

  Thus mounted, the locking member defines a rest position, corresponding to the release of the actuating means 9a, 9b, in which the cord strands 5a, 5b are sheared by the wedging means 8a, 8b.

  The blocking member also defines a release position corresponding to a compressed position, in which the actuating means 9a, 9b are pressed against each other against the elastic element 10, in such a way that the wedging means 8a, 8b release the cord 1 and allow it to slide freely in the adjustment member 6.

  Advantageously, the compressible elastic element 10 has a stiffness sufficient to maintain the cord 1 blocked, but not too great, so that the intensity of the pressure to be exerted on the actuating means 9a, 9b to compress the spring 10 is not too strong.

  According to a preferred embodiment of the invention shown in FIGS. 3 to 6, the adjusting member 6 and the locking member 7 are formed by two open shells 7a, 7b, respectively forming an upper shell 7a and a shell lower 7b. Each shell 7a, 7b has a substantially planar face 20a, 20b, for example oval, from which extends a fallen peripheral edge defining side walls 25a, 11b.

  According to the invention, the side walls 11a, 11b form an outer side wall 11a intended to surround an inner side wall 11b (FIGS. 4, 5 and 6).

  The shells 7a, 7b are of paired geometrical shapes, the upper shell 7a being of general dimensions greater than the lower shell 7b, so that they can be nested one inside the other axially to form a substantially closed housing 30.

  According to this variant, the wedging means are formed by at least one pair of openings 8a1, 8b, formed in each of the shells 7a, 7b, 1i0 precisely through the side walls 11a, 11b.

  According to this variant, the faces 20a, 20b respectively form a front wall 20a and a rear wall 20b, the latter constituting the actuating means (FIGS. 3, 4 and 6).

  According to this preferred embodiment, the elastic element 10 is interposed between the front 20a and rear 20b walls, so that each of its two ends 10a, 10b bears against one of the inner faces of said walls (FIG. 3). Thus mounted, the compressible elastic element 10 exerts a force tending to move the shells 7a, 7b relative to each other.

  Advantageously, the compressible elastic element 10 is preferably a compressible foam or a spring, as shown in FIG. 3. A guiding means 12 such as a cylindrical stud on which the turns of the spring, located on the inner face of at least one of the front walls 20a and 20b of the shells 7a, 7b makes it possible to position the spring 10 and to keep it stationary within the locking member, in order to prevent repeated manipulations. do not move, thus obviating the ease of manipulation of the adjustment member 6. To enhance this effect, two guide means 12a, 12b can be positioned on each of the inner faces of the front walls 20a and 20b rear shells 7a, 7b (Figure 6).

  Advantageously, the rear wall 20b of the housing is intended to bear against the body of the user. For this reason, the edges of the case will preferably be rounded, to avoid any risk of injury.

  According to the invention, the pair of openings 8a ,, 8b, first comprises an upper opening 8a, formed in the outer side wall 1a, and a lower opening 8b, formed in the inner side wall 11b. These openings 8a, 8b, are made such that when the actuating means 20a, 20b are compressed and the shells 7a, 7b abut against each other, that is to say when In the first embodiment of the present invention, the paired apertures 8a, 8b are aligned in such a way as to allow the sliding of the cord 1 passing through through said openings (Figures 4 and 6a).

  The paired openings 8a, 8b are also arranged to be substantially non-aligned when the actuating means 20a, 20b are released and in the rest position, so as to shear said strands by relative displacement of the paired apertures. 8a, and 8b, (Figures 5 and 6b).

  Preferably, the periphery of the openings 8a ,, 8b, will be shaped so as not to cut the cord 1 during the shear of the latter. For this purpose, the thickness of the side walls 1a, 11b of the shells 7a, 7b in which are formed the openings 8a1, 8b, may be of the order of 0.8 millimeter.

  Advantageously, the assembly formed by the shells 7a, 7b provided with the openings 8a1, 8b1, by the compressible elastic element 10 and by the cord 1, this magnetizes the noise. As a result, the openings 8a1, 8b, formed in the upper and lower shells 7a and 7b, act as a connecting element between the two shells, without the need to assemble them by means of an additional connecting element, as is the case of known prior art devices.

  According to another embodiment of the invention, the wedging means are formed by two pairs of openings defining a pair of entrance openings of the cord 8aj, 8b1, said pair being intended to be traversed by one of the two strands. 5a or 5b of the cord 1, and a pair of cord exit openings 8a3, 8b3, substantially opposite the inlet openings 8aj, 8b1, and each intended to be traversed by the corresponding strand 5a or 5b of the cord 1.

  According to an even more preferred embodiment of the invention shown in FIGS. 3 to 6, the wedging means comprise four pairs of openings defining two pairs of entrance openings of the cord 8al, 8b, and 8a2 8b2, each pair being intended to be traversed by one of the two strands 5a or 5b of the cord 1, and two pairs of cord outlet openings 8a3, 8b3 and 8a4, 8b4, respectively substantially vis-à-vis the inlet openings 8aj , 8b1 for the first pair and inlet openings 8a2, 8b2 for the second pair, and each intended to be traversed by the corresponding strand 5a or 5b of the cord 1.

  In order to facilitate the insertion of the cord 1 into the openings of the adjusting member 6, each pair of inlet openings 8a1, 8b1 or 8a2, 8b2 will preferably be arranged opposite one of the two pairs of cord exit openings 8a3, 8b3 or 8a4, 8b4.

  Thus, when the user presses the actuating means 20a, 20b against each other in the direction of the arrow shown in FIG. 3, the elastic element 10 is compressed and each opening of the same pair is is substantially aligned with the second opening, so as to allow the sliding of the strand 5a or 5b. Conversely, when the user releases the actuating means, the elastic element 10 resumes its rest position and the openings of the same pair are shifted so as to shear each of the strands 5a, 5b of the cord 1 .

  The use of four pairs of openings 8aj, 8b1, 8a2, 8b2, 8a3, 8b3, and 8a4 and 8b4 according to this preferred embodiment, makes it possible to secure the blocking, since four jamming means act simultaneously, of which two on the same strand of cord.

  According to an even more preferred embodiment, the adjustment device also comprises means for locking the distance between the cups 4a, 4b of the bra.

  These locking means are formed by a plurality of protuberances 14 positioned at preferably substantially regular intervals along the bead 1, on a portion of the latter located towards the adjustment member 6, or preferably substantially the entire length of the cord 1 (Figures 1 and 6a and b).

  The cord 1 is then formed by a flexible filiform body 13, on which the protrusions 14 are fixed or formed. The latter must have dimensions that are compatible with the openings in the adjustment member 6. Indeed, the cord 1, provided with protrusions 14, must be able to slide freely within the openings. Thus, the cord 1 provided with the protuberances 14 will preferably have a maximum cross-section of dimensions smaller than the size of the openings.

  Furthermore, any geometric shape is possible for the protrusions 14, but they will preferably be spherical, as the openings 10 formed in the side walls 11a, 11b will preferably be substantially circular.

  Thus, as shown in Figure 6a, when the user presses the actuating means against each other, the openings in the side walls 11a, 11b are aligned and facing each other, in such a way that the cord 1 provided with the protuberances 14 can slide inside the adjusting device 6. It is then sufficient for the user to make a pull on the upstream or downstream part of the attachment strands 5a, 5b , so as to adjust their length, which amounts to adjusting the distance between the cups.

  On the other hand, since the user releases the pressure exerted on the actuating means, the paired openings are offset from one another so that they are no longer aligned axially and are sheared off. cord by the substantially opposite zones of their perimeter 1 6a, 1 6b, substantially in the area between two successive protrusions, so as to ensure the locking of the device (Figure 6b).

  The cord 1 provided with such protuberances 14 allows easy identification of the "ideal" positions of the strands 5a, 5b relative to the adjustment member 6, so that the user can move very quickly from a comfort position to a more sustained holding position and vice versa. It is conceivable, in order to make it even easier to locate, to use excrescences of different colors or of different shapes.

  According to a preferred embodiment of the cord 1 provided with the protuberances 14, the body 13 of the cord will preferably be made of a metal material forming the core of the cord and the protrusions 14 will also be made preferably with a material metallic.

  This choice of material makes it possible to ensure a good resistance of the cord to the constraints while retaining its properties of flexibility.

  According to the invention, the protuberances 14 may either be contiguous or, preferably, slightly spaced, thus allowing fine adjustment of the distance between the cups.

  According to the embodiments of the invention presented above, the adjusting member 6 is removably mounted relative to the cord.

  This type of assembly allows the user to remove the adjustment device when for example it wants to wash the bra. Indeed, the adjusting member 6 can be made from decorative materials and therefore expensive, such as gold, and can also be set with precious stones, which may deteriorate in contact with detergents or when they are subjected to mechanical shocks resulting from washing operations.

  The device according to the invention can therefore be used to ensure the adjustment of the distance between the cups of a bra, so as to allow the user to change at any time this distance according to the desired comfort.

  Compared to the devices of the prior art, the device according to the invention allows a very easy grip and manipulation on the part of the user, even when the parts to be handled are very small, so that the Adjusting the distance between the cups of the soutiengorge is fast and easy.

  Another advantage of the object of the invention is to improve the fineness of adjustment of the distance between the cups, thanks in particular to the absence of friction between the openings and the cord when the latter is intended to slide, and on the other hand thanks to the regular spacing of the excrescences mounted on the cord according to the preferred embodiment.

  Finally, another advantage of the device according to the invention is not to require, unlike the previous device, additional connecting means between the parts of the assembly, so that it is <autoaintient.

  According to the invention, the adjustment method of the device for adjusting the distance between the cups 4a, 4b comprises at least one pressing step, by pressing the actuating means against each other, preferably at two fingers (for example the thumb and the wearer's index finger), allowing the paired openings to be aligned.

  The method also comprises a step of adjusting the length of the strands 5a, 5b, so as to adjust the distance between the cups 4a, 4b. This last step must be performed while the step of compressing the actuating means is not completed.

  The adjustment method finally comprises a step of releasing the pressure exerted by the fingers on the actuating means, so as to break the alignment between the paired openings and to wedge each of the strands 5a, 5b in the interval between two successive protrusions 14 thus ensuring the locking of the device.

  According to the invention, the method also comprises, prior to the setting of the device, a step of fixing the cord 1 or half-cords on the side edges vis-à-vis 3a, 3b of the cups 4a, 4b.

  An advantage of this method is that it allows a quick adjustment of the distance between the cups of the bra.

  Another advantage of this method is that it allows a fine adjustment of the spacing between the cups.

  A locking cord 1 of an adjustment device according to the invention, intended to be used in association with the device mentioned above, is characterized in that it comprises a plurality of protuberances 14 positioned at substantially regular intervals on substantially the entire length of the strands 5a, 5b of the cord.

  The cord thus formed then has a plurality of notches 17 at which locking takes place.

  An advantage of the cord according to the invention is to allow the locking of the adjustment member once the distance between the cups soutiengorge adjusted by the user.

  Another advantage of the cord according to the invention compared to the cords of the prior art is that it allows, thanks to the notches made throughout its length, to locate the ideal positions of the notches vis-à-vis the body of adjustment, so as to allow the user to systematically find the ideal length of the cord strands allowing it to obtain the desired comfort.

  Finally, another advantage of the cord according to the invention compared to the cord of the prior art is that it has great strength vis-à-vis the constraints, although retaining all the flexibility of the cords of the art 1 0 prior.
