Definitions

  • a watch band comprising a band element or elements adapted to carry a watch and present opposite free ends, and a clamp pivotally connected with one end of said free ends and adapted to removably receive the other of said free ends, wherein said clamp is of a type including two hinged plate elements adapted to be folded or unfolded for fitting the band around the wrist or releasing the band from the wrist, wherein said other free end of said band element is freely movable relatively to said clamp when said two hinged plate elements are unfolded and is firmly caught by said clamp at any desired position relative to said clamp when said two hinged plate elements are folded.
  • This invention relates to a watch band, and more particularly a watch band which provides a ring of any desired peripheral length to fit around the wrist of any person and to allow it to be removed from the wrist readily bypassing over the hand.
  • Another object of this invention is to provide a watch band which is fundamentally a piece of strip presenting two cooperating ends adapted to be engaged with each other to provide a ring but is usually kept in the form of a ring of variable peripheral length for the convenience of handling. 7
  • Still another object of this invention is to provide watch band which provides a ring of any desired peripheral length wherein a clamp firmly holds the desired peripheral length of the ring without causing any damage to a band portion which is subject to firm clamping by the clamp.
  • FIG. 1 is a perspective view of the clamp portion of a watch band, showing the clamped conditon;
  • FIG. 2 is a longitudinal section of the clamp portion shown in FIG. ll;
  • FIG. 3 is a perspective view of the clamp portion shown in FIG. 1, but showing unclamped condition
  • FIG. 4 is a longitudinal section of the clamp portion shown in FIG. 3;
  • FIG. 5 is an exploded perspective view of the clamp shown in the preceding figures.
  • FIG. 6 is a perspective view of the clamp portion wherein a modification is embodied as compared with the embodiment shown in FIGS. l to 5;
  • FIG. 7 is an exploded perspective view of the clamp shown in FIG. 6 and 7.
  • reference numerals ll, la designate a pair of cooperating band elements of non-extensible character, which are connected respectively at one end thereof to the frame of a watch (not shown), and are adapted at the other end to be clamped together by a clamp generally designated by reference numeral 2, wherein the band element la is pivotally connected with the clamp 2 and the band element 1 is passed through the clamp 2 to be held thereby.
  • the clamp 2 includes a main frame 2a (see FIG. 5) which is formed of side plates'3, 3 and a bottom plate 4 connecting the side plates. At the side platesfi, 3 there are formed two pairs of openings 5, 5 and 6, 6.
  • a pressing plate 7 having projections 7a, 7a at opposite sides thereof is held between the sides plates 3, 3 with the projections 7a, 7a
  • the openings 6, 6 carry a pin on which is pivotally carried a clamping plate 9 having a width closely fitting the space between the side plates 3, 3.
  • the clamping plate 9 has at one end thereof a bearing groove 10 in which the pin 8 is received and a projection 11 adapted to push the upper side of the pressing plate 7 when the clamping plate 9 is turned to the clamping position as shown in FIGS. I and 2.
  • a cover plate 12 At the other end of the clamping plate 9 is pivotally connected by a pin 13 a cover plate 12 of a moderately curved shape which follows over the similarly formed clamping plate 9.
  • the cover plate 12 is formed with a folded end 114 slightly projecting beyond the bearing portion received by the pin 13, so that the folded end I4 provides a means to be caught by a nail when the clamp is unlatched.
  • the cover plate 12 Adjacent the other end, where the cover plate 112 is pivotally connected by a pin 16 with the band element 1a, the cover plate 12 is formed a bent-out projection 15 which is adapted to engage with the end of the clamping plate 9 when the clamp is latched.
  • the band is applied around the wrist with the clamp being unlatched as shown in FIGS. 3 and 4.
  • the free end of the band element 1 may be preliminarily engaged into the clamp 2 as shown in FIGS. 3 and 4 before the band is applied around the wrist by being passed over the band, or may be engaged into the clamp 2 after it has been wound around the wrist.
  • the clamping plate 9 is turned around the pin 8 anticlockwise direction as seen in FIG.
  • the projection ll of the clamping plate 9 presses the pressing plate 7 downward so that the latter would turn clockwise around a hearing axis defined by the engagement of the projections 7a, 7a with the openings 5, 5, whereby the free end of the pressing plate 7 is pressed against the band element I laid on the bottom plate 4.
  • the free end of the pressing plate 7 is elastically bent for a little amount so that the band element 1 is firmly held between the bottom plate 4 and the pressing plate 7 under an elastic force exerted by the pressing plate 7 which is formed as a spring plate.
  • the free end of the band element 1 is provided with means for provisionally preventing the removal thereof from the clamp 2.
  • the free end of the band element 1 is provided with a channel-shaped end frame 17, in which is housed a spring plate 18 having a projecting portion 18a so that the projecting portion 18a normally protrudes through an opening 17a of the end frame 17.
  • the height of the projecting portion 18a protruding above the surface of the end frame 17 is so designed that it normally engages with the edge of a notch 4a formed at the bottom plate 4.
  • a watch band comprising a band element or elements adapted to carry a watch and present opposite free ends, and a clamp pivotally connected with one of said free ends and adapted to removably receive the other of said free end, characterized in that said clamp comprises two plate elements pivotably connected together, the opposite free ends of said pivotably connected plate elements being pivotably connected at one end with said one free end of said band element and pivotally connected at the other end with a main frame of said clamp, said main frame presenting a passage for said other free end of said band element, wherein said passage is defined by a bottom plate of said main frame and a pressing plate pivotably mounted on said frame, and wherein said pressing plate is urged toward said bottom plate by a projection provided at one of said two plate elements according to a rotation of said one plate element when said two plate elements are folded and overlaid onto said main frame when said clamp in brought into a clamping condition, said passage being formed with a converging taper extending toward the free end of said pressing plate to thereby bind said other free end of said band element
  • a watch band according to claim 1 wherein said clamp includes snapping latch means for causing said two plate elements to be overlayed as aforesaid onto said main frame and to be held in their said folded condition.
