Description

The present invention relates to a wristwatch for a watch in a support

  least one layer, which consists of a looped portion and a hole-shaped portion and coupling elements for a coupling device between the looped portion or the hole-shaped portion and the housing of a shows as well as coupling parts of a connecting device between the looped part and the loop, o an individual synthetic part

  is connected to the support by a forming process.

  Already known are wristwatches according to EP-OS 0 199 708 whose support has at least one layer and which consist of a part with loop and a part with holes The part with loop and the part with holes holes have coupling elements of a coupling device by which the looped part or respectively the part with holes is fixed to a watch case. Furthermore, a coupling part of a connecting device is provided between the looped part and the loop A separate part made of synthetic material, for example a continuous layer of synthetic material, is connected to the support by forming process This wristwatch required

  the continuous coating of the support to be able to produce a wristwatch.

  The present invention has the task of creating a wristwatch in which the characteristics of the support can be linked to a secure connection between

  the bracelet and the case of the watch.

  The task of the invention is solved by the fact that a continuous lateral edge of the looped part and / or the hole-shaped part is connected at least partially to an anchoring element which is formed therein and which consists of a synthetic material, which is connected by shape connection with the coupling element or the coupling part of the coupling device or respectively of connection In this solution, it is advantageous that from now on the characteristic features of the support as for example, its breathing activity, its compatibility with the skin as well as its appearance of natural leather can be related to the multiple configuration possibilities and to the high strengths of a coupling part or a coupling element respectively. In addition, it is surprising that, thanks to the shaping of anchoring elements extending over at least a part of the length of the in part with buckle or the portion with holes, one can obtain retentions or respectively traction bands for a fairly solid anchoring of the coupling parts or respectively of the coupling elements on supports which are at a higher level than the tear resistance of the single cross-section of the support In this way, it is also possible to use supports which have very large clean expansions or respectively a minimum resistance to the notches or respectively the perimeter of the holes, advantageously as that support for such wristwatches Thus, it is possible, for example, to use, as a support, despite its lack of resistance, a layer of leather well adapted to a

  surface design for use as an aesthetic element.

  According to another advantageous configuration, the anchoring element and the coupling element or respectively the coupling part are formed in one piece in the same material and are shaped on the part with loop or respectively with holes; thus, several successive working processes can be combined into one, which allows the removal of various handling times as well as the occupation time of the machine to thereby give an inexpensive manufacturing process Given the unique process of implementation form, the support or respectively the multi-layered strip is subjected to the current bonding points, at a regular thermal load, which makes it possible to avoid a unilateral deformation or shrinkage in a secure manner. formed with each other, which also avoids the various points of separation that would occur with

successive formatting.

  An embodiment is also advantageous in which the traction bands of the anchoring element, running parallel to the lateral edges, are connected to each other by transverse bars protruding on the support surface or respectively which there In this way, a stable coherence is obtained along the lateral edges of the support as well as a greater protection against damage and, thanks to the transverse bars which connect the traction bands, a higher resistance to wear is obtained.

  tear transversely to the longitudinal extension of the retaining element.

  But an embodiment is also possible in which between the two traction bands are arranged reinforcing elements or respectively a continuous reinforcing element provided with interruptions or openings respectively passing in the longitudinal direction of the part with loop and / or with holes on at least one of the two surfaces; thus, the reinforced support of the traction bands can be further reinforced in the middle of the band or the bracelet, in the zone of the openings, which are traversed by the barb of the buckle but are subjected there to a greater stress on the

around the holes.

  Another configuration is also possible in which the reinforcing element passes through the support and is provided with at least one interruption or aperture therethrough and advantageously exceeds at least one of the two opposite surfaces; this ensures, even in the case of a multi-layer support, in the area of the openings for the barb of

  the loop, a stable coherence of the individual layers.

  In the same way, another configuration is also possible in which the part with the loop and / or with the holes is provided at its two frontal frontal zones, in each case, with a coupling element and / or a coupling part; thanks to this configuration, a stable support arrangement is created in a simple manner for the coupling or connection device which has characteristics that are considerably

  higher resistance than the support.

  Another configuration is also advantageous in which the coupling element or the coupling part is preferably in one piece and has a receiving bore extending transversely to the longitudinal extension of the looped portion or respectively with holes and parallel to its surface for another coupling element formed by an anchor, or respectively another coupling part; thanks to the configuration of the reception bores, there is a simple way of an arrangement ready for other elements

  coupling or coupling parts respectively.

  An embodiment is also advantageous in which the coupling element or the coupling part is reinforced with a reinforcement part, in particular a very strong plastic part or a metal part or a sleeve; thus, the material for the parts which are formed on the support should for example have only a high tensile strength and the reinforcing part thus protects the material against abrasion and friction stresses. Another arrangement is possible according to which the reinforcing part is provided with anchoring elements protruding in the direction of the traction bands, which are embedded in the synthetic material forming the coupling element or the coupling part and the strips respectively. where respectively they are surrounded by it; thus, the anchoring elements connected to the reinforcement part can absorb, in the connection zone which preferably represents a weak point in the retaining element, a more

great pulling effort.

  Another configuration is also possible in which the traction bands or respectively the coupling elements or the coupling parts protrude at least on one surface of the part with loops and / or with holes; it is thus possible that the cutting edges of the support have a clean finish in the visible area and thus, during the cutting process, no

  important quality requirement is imposed on the cutting edges.

  Another configuration is advantageous in which the support is formed of a leather strip or textile in a layer because thus it is possible to use simple materials and inexpensive to manufacture by a cutting process without significant conditions imposed on the quality because through the process

  formatting that follows, the cutting edges are hidden from the visible area.

  According to another alternative embodiment, the support may be formed of a sandwich element with several layers of materials advantageously different, for example, leather, textile, synthetic material or metal, therefore, the part with loop or respectively the part with the holes made of desired materials, can connected to each other in a simple way and on the same level and the side edges resulting from the subsequent cutting process

  do not have to be covered by a complicated and expensive process of coating.

  According to another configuration, it is advantageous that the traction bands and / or the coupling element or respectively the coupling part cover the support from the continuous lateral edges in the middle direction of the band or bracelet; because, especially in the case of a multilayer carrier, which may consist of a material that is not very resistant to traction, the tensile stress is taken up by the added parts and there is simultaneously a stable connection between the parties

  added and with the layers on the top surface of the support.

  An alternative embodiment is also possible in which the support is provided, in the region of the continuous lateral edges, with a projection which has a smaller thickness with respect to the support and which is surrounded by the synthetic material of the element. anchor; thus, particularly in the case of rather thick supports, there is an additional protrusion of the parts which are added thereto, which offers advantages from the point of view of stability and simultaneously has the effect of saving material in the parts which are

added by formatting.

  According to another variant embodiment, a transition zone between the coupling element and the support has, in the longitudinal direction of the

  wristwatch, a wavy shape; thus, in the case of the load of the bracelet-

  shows in the longitudinal direction, the forces which are presented must not be absorbed by the support or respectively the anchoring elements and there is

  hence no excess of solicitation of these parts.

  Another configuration which is also possible in which the undulating shape of the transition zone is formed of branches which are connected to each other by arcuate elements or respectively of a series of arcuate elements; the following arched elements or the branches have a damping effect during a tensile load and this is

  concretized by an elastic modification of form.

  Finally, an alternative embodiment is also advantageous in which an extension of the transition zone protruding in the direction of the support is partially surrounded by the support; it is thus possible to obtain a stable and tensile bonding zone between the support and the coupling element. The invention will be better understood and other purposes, features, details

side and in section.

  In FIG. 1 is shown a retaining element 1 in the form of a band or bracelet, which is formed, in the present embodiment, of a part 2

  with buckle and part 3 with holes, which together form a bracelet-

  shows 4 The part with loop 2 and the part with holes 3 of the watchband 4 are connected preferably articulated by a coupling device 5 to the housing 6 of a watch 7 Front end zones 8, 9 of the parts with loops or respectively with holes 2, 3 have, in the area of the coupling device 5, coupling elements 10 which are traversed by a pin 11 of a support arrangement 12 While in the front end zone 13 of the loop portion 12 which is remote from the watch 7 are housed a loop 14 with a pin 15 which belongs to it, via a connecting device 16 in the coupling portion 17, the portion of the holes 13 presents in the front end zone 18 away from the

  shows 7 openings 19 therethrough, for the barb 15.

  The part with loop and / or holes 2 or 3 consists of a support which is surrounded, along its lateral edges 21 to 24, all around, anchoring elements 25, 26 which can be configured as bands of The anchoring elements 25, 26 or respectively the traction bands 27 to 30 are advantageously connected in one piece with the coupling elements 10 or respectively the coupling part 17. It is also possible for the anchoring elements 25 , 26 or respectively the traction bands 27 to be arranged only in selected partial areas along the lateral edges 21 to 24 on the retaining element 1 This is different from one case to another according to the various conditions In order to obtain partial zones having different tensile strengths or flexural strengths, a cross-sectional modification of the tension strips 27 to 30 in the longitudinal direction of the element Retention 1 also makes it possible to obtain this desired effect, but, in addition, protection is obtained from all

  sides of the side edges 21 to 24.

  In addition, on the part 2 with loop is arranged a stationary passer 31

as well as a mobile passer 32.

  The openings 19 arranged in the portion with holes 3 for the pin 15 are provided in a reinforcing element 35 protruding from the support 20 and

  advantageously surfaces 33, 34.

  FIG. 2 shows the front end zone 9 of the part 3 with the holes with the support 20, which has a width 36 and a thickness 37 and is framed on the lateral edges 23, 24 by the traction bands 29 The support 20 is provided, in the present embodiment, on its two surfaces 33, 34, in addition, with aesthetic layers 38, 39. 30 pass, over a width of cover 40, over the width 36 of the support 20 in the direction of the medium 41 of the band and thus effectively protect the side edges 23, 24 disturbing influences The opening 19 for the pin 15 is, in this case reinforced, in the part 3 with the holes of the retaining element 1, by a reinforcing element 42 which protrudes on the surfaces of the aesthetic layers 38, 39 The coupling element 10 is connected in one piece with the two traction bands 29, 30 in the end zone 9 of the portion 3 having the holes A receiving bore 43 in the coupling element 10 passes through the portion 3 with the holes in a direction perpendicular to its median longitudinal axis 44 and is used to receive the

  ankle 11 for the support arrangement 12.

  The width 45 of the coupling element 10 can thus be simply adapted to the connecting sides of the coupling device 5 in the housing 6 of the watch 7. Moreover, it is also possible to obtain, thanks to the various widths of the support 20, a different width of the retaining element 1 on its longitudinal extension This is primarily for the

  optical and aesthetic configuration of the retaining element 1 according to the invention.

  As a result, it is possible, for example, in a simple manner to make the retaining element 1 of a width smaller than that required by the coupling device 5 or

  respectively the coupling member 10 having the width 45.

  FIGS. 3 to 5 show various possibilities of producing the retaining element 1 or respectively the parts 2 with the loop or 3 with the holes. In addition, the support has a width 36 transversely to the longitudinal extension and a thickness In the middle 41 of the strip is arranged the opening 19 for the pin 15 of the loop 14 which passes through it. On the lateral edges 23, 24 of the support 20 is again formed the anchoring element 26 in the form of The traction bands 29, 30 have a substantially round cross-section with a diameter 46 which, in this embodiment, exceeds the thickness 37 of the support 20 on both sides, but support 20 does not exceed in the direction of the

middle 41 of the band.

  But it is also possible, as can be seen in Figure 4, to configure the traction bands 29,30 on their vertical extension, so that they are on the same level as the surfaces 33, 34 of the support having the thickness 37, along the lateral edges 23, 24 The cross section of the anchoring elements 25, 26 can be made in the most various forms, for example as circular, elliptical, triangular or rectangular It depends on the purpose of use , conditions of use and

  than the optical and aesthetic configuration.

  FIG. 5 shows part 3 with the holes with the reinforcing element 42 arranged in the middle 41 of the strip and the opening 19 provided therein for the barb 15. Part 3 with the holes is composed in this case of a multilayer sandwich element 47 which is formed of the support 20 and advantageously of layers arranged on both sides 48, 49 The layers 48, 49 may again have a construction in several thicknesses and of various materials such as, for example, synthetic material, textile or the like to be connected to the support 20 by means of a layer of glue 50 shown in dashed lines to obtain stable coherence in the region of the opening 19 of the sandwich element 47 an interruption 51 is provided with a diameter 52 which is larger than the opening 19 The interruption 51 is traversed by the reinforcing element 42 and advantageously has at both ends of the interruption 51, horizontal extensions which exceed 53, 54, the reinforcing member 42 may be manufactured, in the embodiment shown, for example, by a process of injection or foaming there, unlike the embodiment shown in Figure 1 of the reinforcing element 35, at each opening 19 is assigned its own

reinforcing element 42.

This can, for example, occur in the form of ribs passing obliquely or in the form of a network

in latticework.

  FIGS. 8 and 9 show the cross-sections of part 3 presenting the holes which are shown in FIGS. 6 and 7 The opening 19

  is arranged in the reinforcing element 42 passing through the support 20 and that

  ci is connected by the reinforcing element 55 to the traction bands 29, 30.

  As shown here, the reinforcing elements 42 and 55 are arranged only on the upper surface 33 of the support 20. However, as indicated in dotted lines, it is also possible to configure the elements of

  reinforcement 42 and 55 on the surface 34 of the support 20.

  As can best be seen in FIG. 9, the support 20 has, at its lateral edges 23, 24, projections 56, 57 for connection with the traction bands 29, 30, which protrude over a distance 58 beyond the width 36 of the support 20 The thickness 59 of the projections 56, 57 is smaller than the thickness 37 of the support 20 This embodiment is used, above all in the case of very thick supports, to create a better connection, on the side edges,

  between the support 20 and the traction bands 29, 30.

  In Figure 10 is shown the part 2 with the loop by a multi-layer support in the form of the sandwich element 47. In addition, the sandwich element 47 is surrounded on its lateral edges 21, 22 by the sealing strips. 27, 28 which pass over, in the direction of the middle 41 of the strip It results despite the multilayer construction of the sandwich element 47, a safe protection on the side edges 21, 22 against damage or respectively a fraying and simultaneously obtain a tensile-resistant connection between the coupling element 10 and the zone

  end end 18 and / or the front end zone 13.

  Fig. 11 shows the reinforcing member 35 extending in an interruption 60 of the one-to-one openings extending longitudinally of the bore portion in the holder 20. 61, see Figure 1, which is larger than the distance 62 between the first and the last aperture 19, which are arranged one behind the other in a row of holes in the part 3 The edges

  laterals 23, 24 are again reinforced by the traction bands 29, 30.

  The interruption 60 has a width 63 transverse to the longitudinal extension of the support 20 which is smaller than the width 64 of the projections 65, 66 which are on the surfaces 33, 34.

  reinforcement 35, a stable transition towards the support 20.

  FIG. 12 shows the front end zone 8 of the part 2 with a loop with a part of the reinforcement 67 arranged in the coupling element 10. The reinforcing part 67 is of tubular configuration and has the receiving bore. 43 with an internal diameter 68, which serves to receive the pin 11 of the support arrangement 12 for the coupling device 5 A the reinforcing portion 67 are formed of the anchoring elements 69, 70 which are extend from the front end zone 8 in the direction of the front end zone 13 of the loop portion 2 and which are embedded in the traction bands 27, 28 formed on the support 20. in the transition zones 71, 72 to the tensile bands 27, 28, a greater tensile strength is obtained. The anchoring elements 69, 70 must be made of a resistant material at the t However, the looped portion and / or the hole portion 2, 3 from the housing 6 of the watch 7 to the two end-end zones 13, 18 are thus guaranteed.

  will fit well to the user's arm.

  In Figures 13 and 14 is shown another possibility of configuration of the coupling element 10 in the front end zone 9 of the part 3 with holes, where again for identical parts were used the same figures The configuration of the front end zone 9 for the part 3 with the holes is of course also usable in a similar way for the front end zone 8 of the part 2 with the loop. The support 20 of the part 3 with the holes is surrounded, on the side edges 23,24 by the traction bands 29,30 The configuration of the traction bands 29,30 may be in one of the previously described embodiment forms A transition zone 73 between a front edge 74 facing the front end zone 9 of the support 20 and the coupling element 10 which serves to connect the portion 13 with the holes in the housing 6 of the watch 7 is configured in a manner In the present embodiment, the production of the traction bands 29, 30, of the transition zone 73 as well as of the element 2 of the coupling 10 is done in a single working step, which leads to a part of a huge economy and secondly it allows to surround on all sides the support 20 in the front end zone 9, allowing

  to obtain a stable embodiment of the wristwatch 4.

  The transition zone 73 is formed in the present embodiment of a traction element 75 having a wall thickness 76 and is made in the undulated form. Adjacent branches 77,78 of the traction element 75 are connected by an arcuate element 79 and the arcuate element has a

  radius of curvature 80 of between 1 mm and 10 mm.

  If the coupling element 10 with the receiving bore 43 is retained by means of the pin 11 on the housing 6 of the watch 7 and there is a load of the part 3 with the holes in the direction of an arrow 81 from the front end zone 9 to the end end zone 18, due to the inherent elasticity of the traction element 75, the arched element 79 is enlarged between the branches 77,78 and there is therefore in no case an overload of the traction bands 29,30 The return of the traction element 75 to its starting form after the load occurs automatically due to the material used, as for example of the synthetic material in the various embodiments, of itself, since the deformation takes place only in

  the elastic range of the material used.

  As further shown in dashed lines in FIG. 13, a reinforcing member 82 may be arranged in the pulling member 75 to provide an additional increase in tensile strength. This reinforcing member 82 may be made of a carpet, mesh, mesh or mesh fabrics of the most diverse materials, such as, for example, textile, teflon, Kevlar, glass, metal or respectively synthetic fibers or carbon. As best seen in Figure 14, an extension 83 shown in dotted line may be formed on the transition zone 73 which is surrounded by the support 20 or respectively is glued between it. In FIG. 15 is shown a device 84 with its mold halves, 86 and guides 87 for the manufacture of the anchoring elements 25,26 of the coupling element 10, the coupling part 17, the elements of FIG. 35.42 and 55 as well as the traction element 75 The support 20 or respectively the sandwich element 47 is held by means of a retaining and / or positioning device 88 on the lower half of the mold 86 retaining and / or positioning device 88, may, for example, be formed of a vacuum pump 89 which sucks, by means of slots 90, the support 20 The lower mold half 86 is fixed on a base plate 91 on which can also be arranged other necessary devices The upper half 85 is assembled at the lower half 86 into a mold closed to

  by means of lifting and / or closing control along the guides 87.

  In the case where the manufacture of the elements to be molded must occur by an injection process, the necessary material is introduced into the device 84

  by an extruder 93 and lines 94.

  Of course, it is possible, in the context of the invention, to modify at will or to combine in a different way the installations and the individual elements. Similarly, the individual characteristics on the examples shown of embodiment may represent the autonomous solutions according to the invention.

  Finally, it should be pointed out that in the drawings of the example embodiment, individual pieces have been enlarged and schematically simplified for a

  better understanding of the invention.
