Description

March 6, 1956 E. PIQUEREZ FLUIDTIGHT CASING FOR WATCHES Filed Feb. 1. 1954 United States Patent FLUIDTIGHT CASING FOR WATCHES Ervin Piquerez, Bassecourt, Switzerland Application February 1, 1954, Serial No. 407,252 Claims priority, application Switzerland November 2, 1953 6 Claims. (Cl. 58-90) My invention has for its object a fluid-tight watch case. According to a. main object of my invention, the bottom of said case is provided with at least two upstanding tongues extending in parallelism with the axis of the case and fitted on the inside of the case band, said tongues including each an outer shoulder through which they engage, by means of a bayonet joint, a connecting member secured to the case band and projecting inwardly with reference to the latter.
I have illustrated by way of example in accompanying drawings, two preferred embodiments of my invention. in said drawings:
Fig. 1 is an axial cross-section of a portion of a fluidtight watch-case according to a first embodiment;
Fig. 2 is a plan view of the connecting members on a smaller scale;
Fig. 3 is an elevational view of the case bottom, also on a smaller scale;
Fig. 4 is a plan view of the case bottom illustrated in Fig. 3;
Fig. 5 is a cross-sectional view, similar to that shown in Fig. l, of the second embodiment.
Fig. 6 is an elevational view of the connecting member in the second embodiment on a smaller scale;
Fig. 7 is a plan view of the connecting member shown in Fig. 6.
Fig. 8 is an elevational view of the bottom of the case shown in Fig. 5, also on a smaller scale.
In the first embodiment, the fluid-tight case includes a cylindrical case band 1 rigid with the rim, inside which is fitted the glass 2. The case band 1 is provided in its inner wall with an annular groove 3 inside which is housed a spring wire 4 assuming the shape of an open annulus including two sections 4a (Fig. 2) projecting inwardly of the casing and out of the groove 3. The bottom of the case which is independent of the case band, is provided with two upstanding tongues 5a extending in parallelism with the axis of the case and provided each with an outwardly directed flange 5b (Figs. 3 and 4) adapted to engage after the manner of a bayonet joint, the corresponding sections 4a of the spring 4. The surface 6 of each shoulder or flange 5b which engages the spring 4, assumes a frustoconical shape so that the radial pressure exerted by the spring 4 on the upstanding tongues 5a may produce an axial pressure exerted by the bottom of the case on the cooperating edge of the case band 1, said pressure compressing the packing 7 fitted between the said two parts of the case.
In the second embodiment, a flat ring 8 the cross-section of which is rectangular, is housed inside an annular groove 9 formed in the cylindrical inner wall of the case band 10. Said ring 8 is provided, as shown in Figs. 6 and 7, with two projections 8a extending radially and inwardly and the transverse ends of which are folded at 812 so as to further the assembly of the bottom 11 with the case band, through a kind of bayonet joint, said bottom being provided for this purpose, as in the preceding case, with two upstanding lugs or tongues 11a rigid each at its upper end with an outwardly directed flange 11b (Fig. 8) adapted to engage said projections 8a on the ring 8. This embodiment operates thus in the same manner as the first embodiment illustrated in Figs. 1 to 4.
