  • the end attachment for a watch band for use with a wrist watch provided with customary spring bars.
  • the end attachment includes an adaptor which comprises a plate-like member with a generally tubular member at one end adapted to axially receive a spring bar of a watch and a transverse generally rectangular opening through the plate-like member substantially parallel to and adjacent to the tubular member. It also includes a clasp-supporting member, means for securing it to the end of a watch band and clasp means pivotally connected to the clasp-supporting member.
  • the clasp means includes a resilient flange.
  • the resilient flange and the part of the clasp means which extends outwardly from the pivotal connection are passed through the rectangular opening and the clasp means is then moved about its pivotal connection until the resilient flange forms a snap fit with a portion of the clasp-supporting member in which position the end attachment is fully assembled.
  • the user may easily remove the end attachment from an adaptor which has been mounted between the lugs of his watch by merely opening the clasp and withdrawing its outwardly extending part and its resilient flange through the rectangular opening of the adaptor. Consequently the user can change watch bands used with his watch to coordinate his watch band with the clothes to be worn or he can remove his watch band to clean it, without the help of a jeweler.
  • Wrist watch bands are often sold separate from the watches to which they are to be attached.
  • styles in watch bands change more rapidly than styles in watches and watch cases and, during the life of the watch. wearers frequently use several different watch bands with the same watch.
  • Another reason is the preference of the user for watch bands of different types such as leather, fabric, plastic, metal, combinations thereof, snake chain, link chain, mesh, buckle secured, expansible, non-expansible, etc., may change from season to season or at the whim of the person concerned.
  • users desire to wear one style of watch band with the clothes worn during the daytime and another style with clothes worn in the evening.
  • the large majority of wrist watches which are equipped with watch bands are provided with spring pins for attaching the ends of the watch band to the watch.
  • One object of this invention is to provide a novel end attachment for a watch band.
  • Another object is to provide an easily removable end attachment for a watch band which is adapted to be mounted between spaced lugs of a wrist watch with a customary spring pin.
  • a still further object is to provide such an end attachment which is easily installable on his watch by an ordinary user.
  • a still further object is to provide such an end attachment which is adapted to be mounted between lugs of wrist watch cases which are spaced different distances apart.
  • Another object is to provide such an end attachment which includes a top shell which can be provided with designs to match the designs of the links of the watch band and which covers the other elements of the attachment when viewed from the top in use.
  • Yet another object is to provide such an end attachment which is not subject to accidental opening when worn.
  • a still further object is to provide such an end attachment which is economical to manufacture and durable in use.
  • the end attachment of this invention includes an adaptor which comprises a generally tubular member adapted to receive a spring pin of a wrist watch, a plate-like member having one end integral with the generally tubular member and the plate-like member includes a transverse generally rectangular opening substantially parallel to and adjacent to the generally tubular member.
  • the end attachment also includes a clasp-supporting member having at least a portion thereof adapted to be positioned in engagement with at least a portion of the plate-like member of the adaptor.
  • the clasp means includes a resilient flange, and the resilient flange and the part of the clasp means which extends outwardly from the pivot means are passed through the generally rectangular opening of the adaptor to close and open the clasp means and, when the clasp means is in closed position, at least a portion of its upper surface is positioned in engagement with at least a portion of the lower surface of the plate-like member of the adaptor and the resilient flange of the clasp means forms a snap fit with a portion of the claspsupporting member, thereby detachably to secure the clasp-supporting member to the adaptor.
  • the end attachment also includes an ornamental top shell the upper surface of which is formed with the design of the upper surfaces of the links of the watch band and means for attaching it to the clasp-supporting member.
  • the top shell includes a longitudinal extension which covers at least the upper portion of the generally tubular member of the adaptor.
  • this longitudinal extension preferably also includes an end portion which at least partially covers at least a portion of the adjacent side of the generally tubular member.
  • top shell also includes side walls having tabs which form the means for attaching the top shell to the clasp-supporting member.
  • the lower surface of the plate-like member of the adaptor is formed with a depressed central portion which receives the clasp means when it is in closed position, so that the lower surface of the clasp means is positioned in substantially the same plane as the side portions of the lower surface of the plate-like member.
  • the clasp means is provided with means adjacent its resilient flange for receiving the fingernail of the user for use in releasing the engagement of the resilient flange with the clasp-supporting member for opening the clasp means.
  • the clasp means forms at least a part of the bottom surface of the end attachment so that in use it engages the wrist of the wearer to prevent accidental opening of the clasp means.
  • the adaptor is assembled with a watch by the jeweler who inserts a spring pin through the generally tubular member of the adaptor and the pintles ofthe spring pin in the cavities or openings of the lugs of the watch.
  • one end of the watch band is assembled with the adaptor. This operation is simple and any user can do it.
  • the end of the watch band is positioned above the adaptor with the clasp means extending vertically downwardly from the clasp supporting member. Then the lower end of the clasp means and its resilient flange are passed through the rectangular slot of the adaptor. Then the clasp means is rotated about its pivotal connection to the clasp-supporting member and its resilient flange is snapped into engagement with a portion of the clasp-supporting member thus closing the clasp and securing the end attachment and one end of the watch band to the adaptor and thus to the watch.
  • the upper surface of the adaptor is in face-to-face engagement with the lower surface of the clasp-supporting member and the upper surface of the clasp is in face-to-face engagement with the lower surface of the adaptor so that a smooth lower surface is formed for engagement with the wrist of the user.
  • the user To open A clasp means and release one end of the watch band from the adaptor, the user inserts his fingernail beneath the tab on the clasp means and lifts the end of the clasp means thereby releasing the snap fit of the flange with the clasp-supporting member, then the clasp means is swung about its pivotal connection until it is in a vertical position and then it is removed through the rectangular slot of the adaptor thus freeing the end of the watch band from the adaptor. The same operation is then performed with the clasp means on the other side of the watch and the watch band is then free from attachment to the watch.
  • Another advantage is that the user can remove his watch band and clean it himself without taking it to a jeweler.
  • This invention is applicable to all types of watch bands which are capable of use with a watch having spring pins and the majority of watches sold today are of that construction.

  • the watch band includes two components the adjacent ends of which are attached together by a conventional open-up buckle (not shown).
  • Each component comprises an elongate strip of plastic material 20, such as polyurethane based material, which is flexible transversely of its thickness.
  • Each strip is formed with a series of substantially parallel grooves 21 extending inwardly from its bottom surface to provide a series of substantially parallel raised elements 22 between the grooves (See FIGS. 5 and 9).
  • Each raised element includes a thicker central portion 22A and thinner end portions 22B.
  • the component also comprises a series of bottom shells 23, each bottom shell having a raised central portion 23A positioned adjacent to the surface of the thicker central portion 22A of a raised element and a depressed end portion 238 positioned adjacent to the thinner end portion 228 of the plastic strip (FIG. 10).
  • the bottom shell also comprises a pair of substantially parallel side walls 23C (FIGS. 4, 5 and 9) positioned adjacent to the side walls of the raised element of the plastic strip with which the bottom shell is associated.
  • the bottom wall of the bottom shell is provided with substantially rectangular openings 23D which are spaced inwardly from its ends as shown in FIGS. 9 and 10.
  • the bottom shells may be made of metal such as stainless steel.
  • the component also comprises a series of ornamental top shells 24 which may be made of metal such as stainless steel or gold-filled material.
  • Each top shell has a top wall 24A positioned adjacent to the upper surface of the plastic strip 20 as shown in FIGS. 5, 6 and 10. It also comprises end walls 248 which extend from the ends of the top wall 24A adjacent to the sides of the plastic strip 20, having end portions 24C which are in face-to-face relationship with the end portions 238 of the bottom shell. It also comprises centrally disposed tabs 24D on the end portions 24C which are rolled or bent into the openings 23D. The ends of the tabs 24D may extend into the adjacent plastic material of the associated raised element 22B of the plastic strip but this is not necessary.
  • Each pair of side walls 23C of each bottom shell are closely adjacent to the side walls of the raised element with which it is associated and consequently each bottom shell is positively located with respect to its associated raised element and this eliminates uneven spacing of the combined bottom and top shells in the finished component.
  • each top shell is directly secured to its associated bottom shell and each pair of combined top and bottom shells are fastened about the plastic strip
  • the bracelet component is formed with a substantially flat bottom surface which is provided by the central portions 23A of the bottom shells and the end portions 24C of the end walls of the top shells and the strip of plastic material is substantially concealed from view by the series of top and bottom shells.
  • Extensions 24E are provided on one side of the top shells and they extend into openings or slots 24F formed in one side of the adjacent top shell to provide an attractive appearance for the outer face of the component.
  • the side edges of adjacent top shells are adjacent to each other to present a substantially continuous upper surface when the component is flat as shown in FIG. 1.
  • each top shell converges as they extend downwardly from its top wall and the bottom shells are narrower than the top walls of the top shells. This provides gaps or spaces at the lower portion of the assembled component as best shown in FIGS. 4 and 5. These spaces permit normal flexure of a bracelet around the wrist while minimizing or eliminating hair pinching or pulling.
  • One element of the end attachment is the adaptor which is shown in place between the lugs 12 of a watch in FIGS. 1 and 3 and detached in FIG. 4.
  • the adaptor comprises the generally tubular member 25A adapted to receive a spring pin of a wrist watch and the plate-like member 258 having one end integral with the generally tubular member.
  • the plate-like member comprises a transverse generally rectangular opening 25C which is substantially parallel to and adjacent to the generally tubular member 25A.
  • the platelike member is provided with a depressed central portion 25D the function of which will be described infra.
  • a self-contained component (FIGS. 8 and 11) is positioned within the generally tubular member 25A of the adaptor.
  • This self-contained component is shown and described in detail in United States patent application Ser. No. 49l,l4l entitled End Attachment For Watch Bands And Self-Contained Component For Use In Making The Same" filed by Stephen F. Bert July 25, 1974 to which reference is hereby made. It comprises a generally tubular member 31 formed from a strip of metal which is bent into generally tubular form to provide a longitudinal slit 32 between adjacent ends of the strip.
  • a pair of tabs 33, 34 are formed from the strip of metal, one adjacent to one end of the strip and the other adjacent to the other end, the ends of these tabs being bendable towards the interior of the generally tubular member 31.
  • tab 33 extends in one direction near one end of the strip of metal and that tab 34 extends in the opposite direction adjacent to the other end of the strip.
  • cutout portions 35 are provided substantially intermediate the ends of the generally tubular member 31 and a tab 38 extends inwardly from the side of one of these cutout portions thereby dividing it into a pair of cutout portions 39 and 40.
  • the self-contained component 30 also includes a pair of coiled compression springs 41 which slide loosely within the generally tubular member 31 and the inner ends of which engage the tab 38 which is bent inwardly of the tubular mem ber 31 and forms stop means substantially midway between its ends.
  • the self-contained component may use a single coiled compression spring without stop means and in still another embodiment, a single coiled compression spring may be used together with a tab such as the tab 38, the end of which is bent inwardly between a pair of coils of the spring to act as stop means to prevent longitudinal movement of the spring with respect to the generally tubular member 31.
  • the self-contained component 30 also includes a pair of generally tubular inserts 42 adapted to slide within the generally tubular member 31.
  • Each insert is formed from a strip of metal and is provided with a generally rectangular slot 43 formed between the edges of the strip of metal, this slot having an open end and an inner end formed by the edges of the pair of tabs 44 which extend inwardly towards each other from the adjacent ends of the strip of metal.
  • FIG. 11 the parts of the preferred self-contained component are shown in positions ready to be assembled. They can be assembled by an automatic machine which simultaneously inserts the springs 41 at opposite ends of the tubular member 31 until their ends abut the stop means 38, simultaneously inserts the inserts 42 at opposite ends of the generally tubular member 31 and moves them inwardly to compress the springs 41 until the inner ends of the rectangular slots 43 pass beyond the tabs 33 and 34 of the generally tubular member 31 and then the ends of these tabs are bent into the longitudinal slots 43.
  • this self-contained component is to permit the adaptor to be mounted between lugs of watch cases which are spaced different distances apart. This is possible because after the spring pin has been inserted the inserts can be moved inwardly against the pressure of the spring means so they are spaced inwardly from the lugs, they are then released and the spring means urges them outwardly into contact with the inner faces of the lugs thus closing the gaps between the outer ends of the inserts and the lugs and centering the adaptor between the lugs, as shown in FIGS. 1 and 3.
  • the generally tubular member 25A of the adaptor is secured to the generally tubular member 31 of the selfcontained component by a pair of tabs 25E and 25F formed on the end of the cutout or slot 25G on the bottom of the generally tubular member 31.
  • the ends of these tabs are bent into the cutout portions 39 and 40 respectively of the generally tubular member 31 of the self-contained component, see FIGS. 2, 4 and 5.
  • the adaptor may be used without any self-contained component by making the generally tubular member of smaller inside diameter and inserting the spring pin through it.
  • Other devices containing spring pressed elements may also be used to permit the adaptor to be used with a close fit between the spring pressed elements and the spaced lugs of watches. I prefer to use the self-contained component because it is the cheapest and most effective device now known to me.
