Description

Breathable bracelet

The invention relates to a bracelet, in particular a watch band, with a,

optionally two-piece, band body, each band body one each

multilayer construction comprising at least one core material layer, a

Lining material layer and optionally has an outer layer.

Different versions of wristbands for watches are known from the prior art, in which devices for ventilation or to reduce a

Sweat formation are provided on the underside of the bracelet when worn on the skin of a wearer.

For example, from DE 41 35 235 AI a leather watch bracelet is known, which consists of a perforated lining leather, an upper leather and a moisture barrier between the lining and upper leather. The moisture barrier layer may be formed as a nonwoven insert which is moisture-proof in the direction of the upper leather and has an increased moisture absorption in the direction of the perforated lining leather.

As a result, an improved Schweißaufnahme- and -abgabefähigkeit the watch strap is achieved and the lining leather is protected from the inside. The disadvantage of this watch strap, that it comes with strong sweat to an accumulation of sweat and the substances transported within the Uhrarmbands, which can not be removed due to the moisture barrier layer to the outside. A ventilation of the lining leather outward is due to its from the upper leather as well as from the

Moisture barrier layer encapsulated layer during wearing not possible.

From AT 364 557 B, for example, a leather watch strap with a substantially I-shaped support made of a material that is resistant to sweat and dirt is known. At the top of the carrier an upper leather is permanently connected to the carrier. At the bottom of the I-shaped support an absorbent insert is provided, which is interchangeably attached to the carrier. Through the insert, a dirt and sweat recording done while an odor nuisance but avoided. The disadvantage of this watch strap is that through this structure, the insert is mounted on the skin of a wearer facing surface of the watch band, so that it is strong

Transpiration to a fluid congestion between the skin of the wearer and the Watch strap comes. Ventilation of the liner during wear is not provided.

From WO 88/02996 A a Kunststoffuhrarmband is known, which is equipped with a coating of textile pile. This is to ensure that the plastic is kept away from the skin and the wearing of the watch bracelet is perceived as more pleasant and healthy. Ventilation of the textile pile coating to prevent perspiration during wear is neither intended nor contemplated.

Furthermore, DE 10 2005 008 806 AI shows a bracelet for watches, in which at the bottom of the bracelet spacers are provided, which rest against the skin of the wearer. Due to the spacers remain when worn between the bottom of the

Wristbands and the wrist of the wearer free ventilation channels, which for one

Circulation of the air and thus serve to cool the wrist in the bracelet area. By designed in a variety of forms or arrangements

Spacer is intended to prevent the formation of sweat on the underside of the tape. In a development of the application, the spacers are bubble-shaped and filled with a temperature-sensitive filling material. This is to ensure that the spacers during wear in a warming of the

Increase the underside of the bracelet and subsequently improves the air circulation through the enlargement of the ventilation channels. The bracelet is in

Longitudinally flexible, so that when tensile stresses occur, the bracelet is extended. Thus, the bracelet fits tightly against the wearer's wrist. The bracelet may further be provided on its underside with a sweat-absorbing or sweat-repellent coating.

A disadvantage of this design is that a ventilation of the bracelet through the upper material is not provided. Furthermore, it is disadvantageous that the bracelet rests only on the spacers on the skin of the wearer. To one at all

To achieve satisfactory cross ventilation of the ventilation ducts, the

Spacers on the underside of the wristband protrude far enough from this. Thus, on the one hand with prolonged wearing in the area of the spacer pressure or

Rubbing on the skin occur, whereby the comfort is reduced adversely. On the other hand, by appropriately large spacers adversely an optical

Overall impression of the bracelet disturbed. It is therefore the object of the present invention to provide a bracelet, in particular a watch band, which avoids the described disadvantages of the prior art and which is designed both breathable, and offers a high level of comfort. The shapely visual impression of known high-quality watch straps must not be adversely changed or disturbed, which represents a further object of the present invention.

This object is achieved in a bracelet according to the preamble of claim 1 with the features of the characterizing part of claim 1. advantageous

Embodiments and developments of the invention are set forth in the subclaims and the description.

Advantageously, in a fiction, contemporary bracelet, in particular a watchband, with one, optionally two-piece, tape body, each tape body each having a multilayer structure comprising at least one core material layer, a

Lining material layer and optionally an outer layer, the adjacent to the lining material layer core material layer ventilation channels, which are each arranged transversely to a band longitudinal direction throughout the entire bandwidth, the ventilation channels are open to the lining material layer at least in sections.

Band body of the bracelet according to the invention are designed at least two layers, wherein the arranged substantially in the middle or optionally at the top

Core material layer has a special meaning. In this core material layer ventilation channels are provided, which serve for ventilation of the lining material layer, which rests when worn on the wrist of the wearer. Advantageously, the lining material layer is a substantially continuous, flat layer, which is particularly comfortably worn directly adjacent to the wrist. The

Ventilation channels within the core material layer are each transverse to

Band longitudinal direction over the entire bandwidth arranged continuously, with each ventilation channel to the lining material layer is at least partially open. Thus, the lining material layer is ventilated through the ventilation channels. An unwanted sweating on the wrist in the area of the adjacent bracelet is thereby reliably avoided. Suitably, in a bracelet according to the invention, the ventilation channels are at least partially open on a top of the core material layer or on the upper layer adjacent thereto when worn.

In this embodiment, the ventilation channels are not only at least partially open at the sides or to the lining material layer, but it is the

Ventilation channels also at least partially open to the upper layer. Thus, in this embodiment, a particularly efficient cross-ventilation or ventilation of the lining material layer within the band body is made possible.

Likewise, in a variant of the invention, it is possible to omit an additional outer layer and to arrange the core material layer directly on the upper side of the bracelet which is visible when worn. The ventilation channels in the core material layer are thus open both to the lining material layer, to the sides of the belt body, as well as to the top of the belt body.

Advantageously, in a bracelet according to the invention, the ventilation channels are arranged along the band body in the longitudinal axis direction at substantially equal distances from each other.

In an advantageous embodiment of the invention, in a bracelet, the core material layer on recesses and / or through holes.

Through holes through the core material layer are used, for example, to receive sewing thread of a fastening seam of the upper and / or the lining material.

Recesses in the core material layer serve, for example, for receiving a closing strap or for transporting the moisture away from the lining material layer to the outside in the surroundings of the bracelet.

Appropriately, in a bracelet according to the Invention the core material layer of an elastic material, preferably made of a NBR rubber, thermoplastic elastomer, flexible PVC, polyurethane and / or mixtures of elastomers with leather fibers.

An elastic material, preferably a NBR rubber, provides numerous advantages in the manufacture of the core material layer. NBR is the abbreviation for nitrile butadiene rubber. The vulcanizates made of nitrile rubber have a high Resistance to oils, fats and hydrocarbons, as well as favorable

Aging behavior and low abrasion. They are used for example for the production of seals, hoses, rubber gloves and rubber threads. In addition to the ease of processing these materials in the design of the core material layer, such elastic plastics are characterized by a particularly high level of comfort. In particular, when the core material layer is covered only by a thin lining material layer and / or a thin outer layer, that is, when the core material layer is palpable through the cover layers, the elastic plastic material of the core material layer is carried by the wearer Wristbands felt to be particularly pleasant and high quality.

It is also conceivable within the scope of the invention to use other elastic materials for producing the core material layer. In particular, in embodiments of a bracelet according to the invention, which is dispensed with a separate upper layer and the core material layer forms the visible upper side of the belt body, particularly high-grade elastic materials or material mixtures, for example mixtures of elastomers with leather fibers, for the production of the core material layer be used.

Likewise, the surface of the lining leather can be perforated or provided with larger, clearly visible holes for improved cross-ventilation. A further variant of the invention relates to a bracelet in which the lining material is attached to an underside of the core material layer of each band body when worn, wherein lateral ventilation channel outlets in the core material layer are uncovered by the lining material.

In this embodiment, lateral ventilation duct outlets of the respective ventilation ducts which run through the entire bandwidth are visible on the sides of the belt body. The ventilation of the belt body or the removal of moisture from the Futtermaterial- layer through the belt body is thus particularly efficient.

In a preferred embodiment of the invention is in a bracelet the

Lining material in each case along its lining material longitudinal edges sharpened laterally extending, preferably wherein the lining material longitudinal edges are flanged and / or recessed in longitudinal recesses of the core material layer.

This embodiment variant has the advantage that the lining material can be fastened particularly shapely to the core material layer or can be integrated in the core material layer.

It is expedient in a fiction, contemporary bracelet, the upper layer forming upper material water vapor permeable and procure breathable.

For example, textiles, in particular functional textiles, or breathable leather materials can be used as the upper material. It is also conceivable within the scope of the invention, a multilayer upper material or an upper material, which consists of several

different materials or mixtures of materials is made to use.

In a variant of the invention, in a bracelet, a leather upper, which is the upper layer, is produced, preferably from a perforated upper leather.

In this embodiment, a wide variety of leather qualities or leather structures are included as an upper material. For example, the upper material may be made of an antibacterially treated and / or water repellent coated leather. Likewise, the surface of the upper leather may be provided with an embossing and / or perforation or with larger, clearly visible holes for improved cross-ventilation. In a further embodiment for solving the fiction, contemporary task is in a bracelet, the upper material at the top of the core material layer each

Attached belt body, wherein lateral ventilation duct outlets in the core material layer from the upper material are uncovered.

A further expedient embodiment is characterized in that in a bracelet the upper material is attached to the upper side and / or to a lower side of the Kernmaterial- layer of each band body and / or is connected to the lining material, wherein lateral ventilation channel outlets are covered by the upper material.

In a further embodiment, the outer material is sharpened laterally extending along its upper longitudinal edges in a fiction, contemporary bracelet, preferably the upper longitudinal edges are flanged and / or recessed in longitudinal recesses of the core material layer.

This embodiment variant offers the advantage that the upper material can be fastened particularly beautifully to the core material layer or can be lowered into longitudinal recesses of the core material layer. Thus, an exact termination of the upper material along its upper longitudinal edges is achieved.

Fig. 1 shows a bracelet 1 according to the invention with a two-part band body 2, 3 on its top visible when worn on a wrist. A band body part 3 has at its one free end a flap part 4 for receiving a clasp. Near the flap part 4, a belt loop 5 is attached to the belt body part 3. At its opposite free end of the band body part 3 is provided with a fastening eye 6 for fastening, for example, on a watch case or on a piece of jewelry. Likewise, the band body part 2 at one of its free ends on a mounting lug 6. Thus, the two band body parts 2, 3 in a conventional manner, for example, with spring pins, which are used in the eyelets 6, to corresponding

Recesses of a watch case or jewelry hinged to this. A watch case, jewelry or the necessary attachment of the tape body parts fasteners are for clarity in the

Illustrations not shown.

Each strip body 2, 3 is constructed in multiple layers and has in each case an outer layer 7, a core material layer 8 and a lining material layer 9.

The core material layer 8 is located between the lining material layer 9 which, when worn, rests against the wrist of the wearer and is visible when worn

Upper layer 7 and forms the core of the bracelet. The core material layer 8 is here made of a core material 8.1 made of NBR rubber. The core material layer 8 has ventilation channels 10, which each have outlets 11 on the longitudinal sides of the

Band body 2, 3 form. The ventilation channels 10 are each transverse to one

Bandlängsrichtung 12 and continuously over an entire bandwidth 13 of

Band body 2, 3 arranged. The ventilation channels 10 are each further to

In addition, in the embodiment of a fiction, contemporary bracelet 1 shown in Fig. 1, the ventilation ducts 10 are also partially open to the upper layer 7 towards sections. Thus, both a very efficient cross-ventilation of the lining material layer 9 to the band sides, as well as a

Ventilation achieved by the core material layer 8 and the upper layer 9 outwardly. Sweat or moisture, which otherwise form in the lining material known from the prior art bracelets and during wear not outward can be removed are transported in the bracelet shown here 1 to the outside or dried by aeration of the belt body 2, 3.

As the upper 7.1 leather is used, which is sharpened along its upper longitudinal edges 7.2 running laterally. The upper longitudinal edges 7.2 are additionally flanged, resulting in particularly elegant longitudinal edges of the upper 7.1. The strip-like arranged upper 7.1 is here formed in each case by a perforated upper leather 7.3. The upper leather 7.3 points along the entire

Longitudinal axis 12 of the two-part belt body 2, 3 a uniformly distributed over the bandwidth 13 perforation to make the upper layer 7 particularly water vapor permeable and breathable.

As shown in FIGS. 1 and 2, the side surfaces of the bracelet 1 and thus the lateral outlets 11 of the ventilation channels 10 remain uncovered. The ventilation channels 10 are arranged along the band body 2, 3 in the longitudinal axis direction 12 at substantially equal distances 14 from each other. Furthermore, recesses 15 are provided for adjustable fastening of a buckle each approximately in mid-band.

Attachment of the upper 7.1 and the lining material layer 9 is provided.

Fig. 2 shows the bracelet 1 shown in Fig. 1 at its abutting when worn on the wrist of the wearer bottom. As a lining material 9.1 here a perforated lining leather 9.3 is used, which is similar to the upper leather 7.3 sharpened along its Futtermaterial- longitudinal edges 9.2 extending laterally. Furthermore, the Futtermaterial- longitudinal edges 9.2 sunk in longitudinal recesses 8.4 of the core material layer 8, as the following Fig. 3 can be seen.

In Fig. 2, a loop anchor 20 is further shown, which is arranged on the band body part 3 near the flap part 4 for receiving a clasp. The loop anchor 20 serves for fastening the band loop 5 and is formed by lateral projections 21 of the core material layer 8. The distance between the two projections 21 to each other on both longitudinal sides of the belt body part 3 each have a width 5.1 of the belt loop 5. Advantageously, the belt loop 5 through the loop anchor 20 in the longitudinal axis 12th

fixed immovably. Furthermore, a second belt loop 5.2 is shown, which is arranged here, for example, in the longitudinal axis direction 12 slidably on the belt body part 3. Thus, the fixed in their position belt loop 5 and the sliding serve Belt loop 5.2 while wearing on the wrist for receiving or fixing the free end of the other band body part. 4

As shown in FIG. 1, ventilation of the core material layer 8 in the ventilation channels 10 in the direction of the arrow 18 is thus effected in each case transversely to the bandwidth 12 by means of the lateral outlets 11. Furthermore, moisture in the direction of transport 19 from the lining material layer 9 passes through the core material layer 8 and further discharged through the upper layer 7 to the outside to the environment.

FIG. 3 shows a detailed view of a core material layer 8 of a bracelet 1 according to the invention. The core material 8.1 NBR rubber is here designed segment-like and has ventilation channels 10 at regular intervals, which are each arranged over the entire bandwidth 13. Several connecting webs 8.5 are used for each

Connection of adjacent segments of the core material 8.1. The connecting webs 8.5 are distributed over the bandwidth 13 and each have intervening

Recesses, through which openings or ventilation channels 10 a

Moisture transport in the transport direction 19 substantially perpendicular to the top 8.2 of the core material layer 8 can be done. Thus, the core material layer 8 is provided with openings both to the upper side 8.2, which is directed towards the outer material when being worn, and to the underside 8.3 oriented towards the lining material. Thus, the cross to the

Band longitudinal direction 12 arranged ventilation ducts 10 with both side outlets 11, as well as openings between the connecting webs 8.5 all sides open to the surroundings of the bracelet 1 out. The ventilation channels 10 are at least partially covered in the finished bracelet 1 with lining material or upper material, as can be seen from the drawings Fig. 4 to Fig. 6.
