REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application is a continuation of U.S. patent application Ser. No. 10/273,255 filed Oct. 18, 2002. 
     
    
     FIELD OF THE INVENTION  
       [0002]     This invention relates to watches. In particular, this invention relates to a bracelet or wristwatch having a decorative housing with arm bands that grasp the arm of the user.  
       BACKGROUND OF THE INVENTION  
       [0003]     Wristwatches are worn by all segments of society. While to an adult the primary function of the wristwatch is to allow the user to determine the correct time, in many cases the wristwatch also serves an ornamental purpose.  
         [0004]     Children in particular will often select a wristwatch for fashion reasons. In some cases a child will wear a watch primarily as a fashion item, and the convenience of having the correct time immediately accessible is either secondary or irrelevant. Children also tend to like a particular wristwatch because it is popular, but at the same time like to be able to wear an item that is somewhat distinctive. Bracelets can be fashionable for the same reasons.  
         [0005]     A parent will often take comfort in knowing that the child is aware of the time and not reliant on others to apprise the child of the time day. To some extent this is a sign of responsibility in a child. Moreover, in the case of very young children it can be considered beneficial to introduce the child to the routine of wearing a wristwatch, or an alternative such as a bracelet, at an early age. It is accordingly advantageous to provide the child with a wristwatch or bracelet which is fashionable, fun to wear, and somewhat distinctive to satisfy most children&#39;s desire to “show off” a unique personal belonging.  
         [0006]     Further, a wristwatch must be put on with one hand. The clasp of a conventional watchband can be difficult to manipulate with one hand, particularly for a child whose dexterity may not be fully developed. Accordingly, despite a parent&#39;s desire to coax their child into the routine of wearing a wristwatch, the child may be unable to put on the wristwatch because only one of the child&#39;s hands is available to operate the clasp, or the child may be frustrated when they encounter difficulty in doing so and may try to avoid wearing a watch.  
         [0007]     It would accordingly be further advantageous to provide a wristwatch that is easy for a child to put on with one hand.  
       SUMMARY OF THE INVENTION  
       [0008]     The present invention provides a wristwatch or bracelet that is decorative, easy for the user to put on with one hand, and conducive to forming part of a thematic collection of many different styles. This provides an item for children to wear that is fashionable, but at the same time different users can possess different variations of the wristwatch or bracelet, all of which being thematically related to the collection.  
         [0009]     The invention accomplishes this by providing a wristwatch or bracelet comprising a decorative housing and opposing resilient armbands that are biased to a closed position and may be pried to an open position to put on the wristwatch or remove the wristwatch from the user&#39;s arm.  
         [0010]     the preferred embodiment, the housing according to the present invention presents opposed pairs of resilient armbands, and the housing is shaped in the form of an animal or character, real or fictitious, with the opposed pairs of armbands being formed as appendages of the animal or character. Thus, a wristwatch according to the invention is particularly suitable for marketing as a “collectible” item, i.e. part of a collection of wristwatches, being produced as part of a line of animals and/or characters, for example cartoon or comic strip characters, while providing a virtually unlimited variety of shapes and styles to thus allow users to collect and wear different variations of the wristwatch or bracelet.  
         [0011]     A wristwatch or bracelet according to the invention is accordingly fun to wear, fashionable, and easy for the user to engage to his or her wrist using only one hand.  
         [0012]     The present invention thus provides a housing for a wristwatch, comprising a body for mounting a timepiece, and at least two opposed armbands extending away from the body, at least one of the armbands being flexible and biased to an engaging position in which the armbands engage around a user&#39;s wrist and moveable between the engaging position and an open position, whereby when the user moves the armband to the open position the wristwatch can be engaged to the user&#39;s arm or disengaged from the user&#39;s arm.  
         [0013]     The present invention further provides a wristwatch, comprising a timepiece, a body for mounting the timepiece, and at least two opposed armbands extending away from the body, at least one of the armbands comprising a resilient member biased to an engaging position in which the armbands engage around a user&#39;s wrist and moveable between the engaging position and an open position, whereby when the user moves the resilient member to the open position the wristwatch can be engaged to the user&#39;s arm or disengaged from the user&#39;s arm.  
         [0014]     In further aspects of the invention: the body is shaped in the form of an animal or character; the armbands are shaped like appendages of the animal or a character; the housing comprises a first pair of armbands in opposition to a second pair of armbands; in which the armbands on at least one side of the user&#39;s arm comprise a core of a resilient material; both armbands are resilient and biased to the closed position; both pairs of armbands comprise a resilient member and are biased to the closed position; the housing comprises a plurality of armbands extending from each side of the body wherein all armbands comprise a resilient member and are biased to the closed position; the body is molded; and/or the resilient members are formed as part of an integral core insert and the armbands are molded over the core insert integrally with the body.  
         [0015]     The present invention further provides a bracelet, comprising a body, and at least two opposed armbands extending away from the body, at least one of the armbands comprising a resilient member biased to an engaging position in which the armbands engage around a user&#39;s wrist and moveable between the engaging position and an open position, whereby when the user moves the resilient member to the open position the bracelet can be engaged to the user&#39;s arm or disengaged from the user&#39;s arm.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0022]     An embodiment of the wristwatch of the invention is illustrated in  FIG. 1 . It will be appreciated that the embodiment of  FIG. 1  is merely one example out of a virtually infinite variety of wristwatch shapes and/or styles that can be produced according to the present invention.  
         [0023]     The wristwatch comprises a timepiece  2  lodged in a housing  10 , which in the preferred embodiment comprises a body  12  formed generally in the shape of an animal or character, which may be realistic or fictitious, for example a popular cartoon character. The body  12  illustrated in  FIG. 1  by way of example only is in the form of a dinosaur body. The body  12  of the housing  10  may be formed, for example molded, from rubber, plastic, silicone or any other suitable material, flexible or rigid, and colored with any desired pigment, paint or otherwise to increase the realism of its appearance. The body  12  may alternatively be formed as a plush figure, made from any available fabric and stuffed in conventional fashion to maintain the body  12  in the desired shape.  
         [0024]     The timepiece  2  may be embedded (in the case of a molded body  12 ) or sewn (in the case of a plush body  12 ) in any convenient position where it is visible to the user when the housing  10  is engaged to the user&#39;s wrist. The timepiece  2  shown in  FIG. 1  by way of example is a conventional digital electronic timepiece, however any desired timepiece may be mounted or affixed to the housing  10  and the invention is not intended to be limited to any particular type of timepiece  2  associated with the watch housing  10 .  
         [0025]     Projecting from the body  12  are opposed armbands  14 ,  16 . In the embodiment shown each watch is provided with a pair of armbands  14  and a pair of armbands  16 , however a single armband  14  and a single opposing armband  16  will also operate effectively accordingly to the principles of the invention, although the wristwatch will not necessarily be as resistant to disengagement as where opposed pairs of armbands  14 ,  16  are used. Further, any number of additional armbands  14  and/or  16  may be included, either to accommodate the design of the animal or character (for example a spider with eight legs) or to increase the resistance to disengagement of the watch from the user&#39;s arm. In alternative embodiments the arm bands  14 ,  16  may be very wide, for example the wings of a bird (not shown) or the fins of a fish (not shown), in which case a single armband  14  and a single armband  16  may be preferable and just as stable.  
         [0026]     The armbands  14 ,  16  are biased to a closed position, either permanently or selectively. For example, each armband  14 ,  16  may comprise a core of a spring member  20 , for example composed of spring steel, which is formed in and thus permanently biased to the grasping position shown in solid lines in  FIG. 1 . The resistance to bending of the spring member  20  is a matter of selection, it being desirable that the wristwatch be held sufficiently firmly against the user&#39;s wrist so as not to disengage inadvertently, while at the same time the armbands  14 ,  16  should be sufficiently easy to bend as to permit a child to pry the bands  14  and/or  16  away from his or her arm fairly readily in order to apply or remove the wristwatch.  
         [0027]     The arm bands  14 ,  16  may alternatively be rigid and pivotally mounted to the body  12 , biased to an engaging or grasping position by a spring or other resilient element; or the arm bands  14 ,  16  may be flexible and formed from a material, or provided with a core of material, which retains its shape under sufficient force to resist disengagement from the user&#39;s arm. In each case at least one of the arms bands  14  or  16  is flexible and biased to the closed position.  
         [0028]     The armbands  14 ,  16  may be formed separately from the body  12  and attached to the body  12  after fabrication. However, in the preferred embodiment an insert  18  comprising spring cores  20  for each of the armbands  14 ,  16  is formed as a single unit, visible in  FIG. 2 . The junction between the spring cores  20  may provide a backing plate  22  for the timepiece  2 , for example with a rim  24  into which the timepiece  2  is mounted in snap-fit relation to prevent dislodgement.  
         [0029]     Where the body  12  is molded, each spring core  20  (or the insert  18  comprising all spring cores  20  extending from backing plate  22 ) is preferably molded integrally with the body  12 , and preferably fully encapsulated in the molding material so as to conceal any sharp edges. In the example illustrated in  FIG. 1 , the rubber body  12  is molded integrally with pairs of armbands  14 ,  16 . The insert  18  comprising spring cores  20  and backing plate  22  is positioned in the mold in conventional fashion so as to be completely surrounded by rubber during the molding process (for example injection molding). Because the rubber is flexible, it does not significantly impede the resilience of the spring core  20  or the user&#39;s ability to pry the bands  14  and/or  16  apart to apply or remove the wristwatch.  
         [0030]     The embodiment in which the spring cores  20  for the armbands  14 ,  16  are formed as a single-piece insert with the backing plate  22 , is also particularly suitable for a plush version of the wristwatch according to the invention. Once the insert  18  has been die stamped (or otherwise cut out) and pressed (or otherwise formed) into the desired position, the orientations of the spring cores  20 , and thus the wristbands  14 ,  16 , are fixed by the backing plate  22  and so do not rely upon the material of the body  12  or filling material for structural strength. Moreover, the backing plate  22  provides a solid surface for mounting the timepiece  2 .  
         [0031]     To manufacture the molded embodiment of the invention, a core insert  18  comprising spring cores  20  for each of the armbands  14 ,  16  projecting from a backing plate  22  is placed in a mold (not shown) and secured in position within the mold by suitable spacing elements (not shown) in conventional fashion. A filler piece is positioned where the timepiece  2  will be mounted, to exclude molding material from the space that the timepiece  2  will occupy. Plastic, rubber or any other suitable molding material is injected into the mold and encapsulates the core insert  18 . The housing  10  thus produced is removed from the mold and the timepiece  2  is mounted to the backing plate  22 .  
         [0032]     In this embodiment it may be advantageous to form the opening in which the timepiece  2  is mounted slightly smaller than the size of the timepiece  2 , so that the resilient molding material will hold the timepiece  2  in position in the finished product. If the molding material is not resilient, other means (for example adhesive or mechanical structures) may be required to secure the timepiece  2  against dislodgement.  
         [0033]     In use, the user positions one of his or her arms against the tips of one of the pairs of armbands  14  or  16 , and pries the other pair of armbands  16  or  14  open so that the arm fits between the tips of the pairs of armbands  14 ,  16 . When the user releases the armbands  14 ,  16  the resilient spring cores  20  draw the armbands  14 ,  16  back to the grasping position, engaging the wristwatch to the user&#39;s arm.  
         [0034]     It will be appreciated that it is possible to form the spring cores  20  so as to lock in the open position, for example in the same fashion as a “slap bracelet”. This can be accomplished by forming each spring core  20  with a slight transverse curvature that must be straightened before the spring core  20  will bend longitudinally. Prying the spring core  20  open to a longitudinally straight position re-establishes the transverse curvature and locks the spring core  20  into a longitudinally straight position. This allows a user to pry the armbands  14 ,  16  to the open position, and then “slap” the wristwatch onto their wrist. The momentum of the open armbands suddenly stopping as the body  12  comes into contact with the user&#39;s wrist overcomes the stiffening effect of the transverse curvature and allows the spring cores  20  to return to the engaging position and grasp the user&#39;s arm.  
         [0035]     It will also be appreciated that the principle of the invention applies even if the armbands  14  or  16  on only one side of the body  12  are resilient or flexible. In this case the armbands on the other side of the body, for example armbands  16 , may be fixed and rigid while the armbands  14  are biased to the closed position but can be pried to the open position. Sufficient clearance will still be available for the user to insert his or her wrist between the armbands  14 ,  16 .  
         [0036]     Various embodiments of the present invention having been thus described in detail by way of example, it will be apparent to those skilled in the art that variations and modifications may be made without departing from the invention. The invention includes all such variations and modifications as fall within the scope of the appended claims.
