Abstract
WATCH CASE ASSEMBLY
Abstract of the Disclosure There is disclosed a watch case assembly having a housing with non-cylindrical interior cavity and a cover with a circular hole therethrough for access to the interior cavity joined together by means of a split connecting ring.
The connecting ring is formed with a threaded portion at one end and an outer flange on the ring at the other end.
Recesses are formed into the interior walls of the cavity of the housing to form shoulders to engage the flange of the connecting ring in the final assembly. The hole through the cover is threaded to mate with the threaded portion of the connecting ring. Thus, in the final assembly, as the connecting ring is screwed into the cover one surface of the flange is drawn up against the shoulders formed by the recesses within the internal cavity of the housing forming a high strength closure of the watch case.

Description
~ackground and Summary of the Invention A typical watch case comprises a housing with an interior cavity and a cover of the same shape as the interior cavity to provide simple closure of the housing. In those few instances where it is desired that the opening to the interior cavity be smaller than, and possibly of a different shape from, the opening of the interior cavity, a cover is typically affixed to thc housin(3 l~y mcalls of macl-inc scrcws. Thcse covcrs ofte define a circular hole therethrough to provide access to the interior of the case. This circular access hole is then provided with an easily installed circular cover to provide complete closure.
~090591 In accordance with one aspect of this invention there is provided an assembly comprising: an integral housing having fixed sides and a non-cylindrical polygonal cavity having at least three sides and a bottom, the cavity opening through one side of the housing with at least one recess in the interior sides of the cavity; cover means for closing the cavity opening of the housing, the cover means having a thread-ed opening therethrough; and a split annular connector means being insertable into the cavity through the open side of the housing and having an externally threaded portion, a flanged portion, and a receptor portion, the externally threaded portion being disposed for engaging the threaded opening of the cover means, the flanged portion being thinner than, and disposed to be freely rotatable within the at least one recess within the cavity of the housing following the inser-tion of the flanged portion by deforming the connector means into a single loop spiral and screwing the flanged portion o7~ /co~ f ~r c reccss .P into the re~c~ within the cavity of the housing, and the receptor portion being disposed to facilitate turning of the annular connector into the threaded opening of the cover means for providing intimate closure of the cover means upon the housing from without the upper surface of the cover means~
In accordance with the illustrated embodiment, the present invention provides a watch case comprising a housing, a connecting ring and a cover with a threaded hole therethrough.
The housing has a non-cylindrical interior cavity with a semi-circular recess in each wall of the cavity located just below the open surface of the housing. The connecting ring has a flange on the outer surface at one end for mating with, and ~' 1~90591 is not as thick as, the semicircular recesses of the housing and a threaded portion on the other end of sufficient length to extend above the open surface of the housing for screwing into the cover.
Additionally, the connecting ring is split to facil-itate insertion of the connecting ring flange into the interior recesses of the housing by mildly deforming the connecting ring and twisting it into place. With the flange end of the connecting ring inserted into the housing, the cover is placed over the housing and the connecting ring is screwed into the cover by means of an appropriate tool. When the case is fully assembled, the flange of the connecting ring is drawn up against the shoulders formed by the recesses in the housing interior, and the screw threads of the cover and the connecting ring become wedged together to provide a high strength closure of the watch case assembly. A
circular cover can then be provided for the remaining circular opening in the assembled case.

Description of the Preferred Embodiment With reference to Figure 1, there is shown a prior art housing having a non-cylindrical interi'or cavity 12 and four cylindrical tapped blind holes 14 located in the corners-of housing 10 and opening to the same surface of housing 10 as cavity 12. Also shown is a cover 16 which has there-through a large, centrally located circular hole 17 and four smaller holes 19 located in the corners of cover 16 with all five holes opening to the same surfaces of cover 16. Cover 16 is attached to housing 10 by means of four screws 18 being extended through holes 19 of cover 16 and screwed into holes 14. I'his assembly is representative of a typical means for restricting the larger opening of housing 10 to the smaller circular opening of cover 16.
Figure 2 illustrates the assembly of the preferred embodiment of the present invention showing a housing 20, a connecting ring 26, and a cover 36. Housing 20, machined from a steel block or another suitable material, has a non-cylindrical, interior cavity 22. Formed into each of the interior side walls of cavity 22 or housing 20 is a semicircular recess 24 centered and located just below the surface of housing 20 onto which cavity 22 opens. The shoulders 42 of each recess 24 closest to the surface of housinq 20 is parallel thereto and in a common plane with each other shoulder of the other recesses 24.
Connecting ring 26, formed from spring steel or another suitable material, has an externally threaded portion 28 and an outer flange 30 that is thinner than recesses 24 are high.
Additionally, connecting ring 26 is shown as being split at 32 for insertion into housing 20 and inCQrporating notches 34 adjacent to threaded portion 28 for tightening connecting ring 26 in the final assembly. Cover 36 has a large, centrally-located, threaded, circular hole 38.
The assembly of the case of the preferred embodiment is shown in Figures 2 and 3. Connecting ring 26 is initially inserted into housing 20. This is accomplished by placing flange 30 of connecting ring 26 in contact with the surface of housing 20 to which cavity 22 opens. Next, one end of connecting ring 26 adjacent to split 32 is depressed into cavity 22, deform-ing connecting ring 26 into a single loop spiral. While maintain-ing the spiral shape, connecting ring 26 is twisted to cause the end of flange 30 depressed into cavity 22 to enter a first recess 24. Connecting ring 26 is maintained in the slightly deformed configuration as the twisting of connecting ring 26 is continued until flange 30 engages all four of recesses 24.
Cover 36 is then placed over housing 20 w th hole 3 being aligned with threaded portion 28 of connecting ring 26j which extends above the open surface of housing 20. An appropriate tool is then insexted into slots 34 of connecting ring 26 and the assembly is completed by turning connecting ring 26 to engage threads 40 of cover 36 with threads 28 of connecting ring 26.
As connecting ring 26 is screwed into cover 36, flange 30 of connecting ring 26 contacts shoulders 42 and split 32 closes as 1~905~1 connecting ring 26 becomes compressed, thus creating a:high-strength closure of the assembly with a smooth exterior surface.
