Definitions

  • the present invention relates to watches and more particularly to a spring bar assembly for watches.
  • Conventional spring bars which are used to join bands or straps to watches have been a source of numerous problems.
  • the spring bar must have outwardly extending projecting members or pins at each end which are readily compressible to facilitate assembly to the watch bezel lugs.
  • the pins must DETAILED DESCRIPTION OF THE INVENTION
  • the invention comforming the member 16 is carefully selected to provide be urged against the bezel with sufficient force to pro vide a secure mounting for the watch.
  • the general solution has been to mount a coiled spring within the body of the assembly to provide a backing for the projecting pins.
  • the assembly comprises a main body portion having a predetermined amount of shaped resilient material, such as silicon rubber, mounted therewithin and pins extending outwardly from each end of the body portion.
  • the pins are slideably mounted for movement within the body portion and are backed by the resilient material.
  • the resilient material is suitably arranged within the hollow body to permit expansion in a direction transverseto the axis of the assembly as the pins are placed under compression.
  • FIG. I is aside view of a watch showing the spring bar assembly of the present invention.
  • FIG. 2 is cross-sectioned view of the spring bar assembly prior to assembly to. a watch showing the resilient material in anon-crompressed state
  • FIG. 3 is a view of the invention taken along the line 3-3 of FIG. 1, and, I
  • F IG. 4 and FIG. 5 represent another embodiment of the invention showing the spring bar in an un-compressed and a compressed state.
  • the member 16 is positioned within the substantially cylindrical interior 1'3 to permit room for uniform expansion during compression.
  • a pair of spring bar pins 17 and 18 are slideably mounted at the ends of the body portion 19, and intermediate portion 2l of lesser diameter and an outer portion 22 of a still smaller diameter.
  • the rear portion 19 of pins 17 and 18 is backed by resilient member 16 while the outer walls thereof are mounted for movement along the interior surface of the body 12.
  • the pins 17 and 18 are retained within the body by the ledge 23 which abuts to engage the bezel lugs 24 with the ledge 26 bearing against the bezel 27.
  • the resilient member 16 is mounted within the body portion. 12 of the assembly 10 leaving a clearance 28.
  • the member 16 expands into the clearance space 28.
  • the resilient member 16 urges the pins 17 and 18 outwardly with sufficient force to securely hold the watch band which. is assembled about the spring bar 10 to the watch 11. This overcomes a serious difficulty with small size spring bars of conventional design wherein coiled springs are unable to provide adequate holding force.
  • the member 16 must be designed so that compression thereof does not distort the tubular body 12.
  • the resilient member 16 may be a hollow slug which is intended to provide stability and eliminate forming while retaining the necessary pressure and resilience characteristics.
  • This em has a hollow interior 30.
  • the spring bar is shown both tion will be more clearly seen when viewed in conjuncin a compressed and non-compressed state.
  • the above-described invention also facilitates construction of the spring bar assembly 10 by eliminating the difficulty experienced in handling small coiled springs.
  • the member 16 in the form of a resilient slug maybe readily inserted within the tubular body 12, the
  • pins 17 and 18 placed thereagainst and theends of the tube crimped over to hold the assembly 10 together.
  • a spring bar assembly for watch-es comprising:
  • a member consisting of a resilient mass of substana pin slideably mounted and retained within each end of the tubular body by the inwardly extending edges, said pins abutting against opposite faces of the resilient member, and,
