NOV. 7, 1939 w FQRSTNER Q 2,178,572
DETACHABLE CONNECTION Filed Feb. 18, 1937 ATTORNEY DETAGHAELE CGNNECTIQN William For-stirrer, East Orange, N. lit, assignor to Forstner Chain Corporation, a corporation or New Jersey Application February 18, 1937, Serial l lo. 126,458 3 Glaims. (Cl. 2l-23il) My present invention relates to the jewelry art Ii6LdlZlg forwardly of the upper portion as and has particular reference to a detachable conind ued at ll to provide bearings for a hinge nection for wrist watch pin it}; the housing lil nests in the cover It, and Detachable connections for small size Wrist both are hingcdly mounted on the pin i8. The
watch straps such as are suitable for use with -.ousing i l is generally of box shape, see Fig. 8, 5 ladies wrist watches, comprise separable sections and is open at the front to provide an entrance, which may be unlocked for permitting removal the base of box having a slightly downwardof the wrist watch from the wrist, and which 1y curved extension it to assist in receiving the are secured together to retain the wrist watch on inserted spring tongue member it, and the up- 10 the wrist. per face 26 of the box having an opening 2| 10 It s the pr ncipal Object of my invention to formed forwardly therein, for the purpose hereimprove the type of connection described, and inafter described. thus insure against accidental separation oi the The cover 55 has its forward end rounded as parts. indicated at 22, a finger engageable tab 23 being It i a further b e t f my invention to p struck up from the stock, the sides 24. of the 15 vide a construction which facilitates the locking cover being 1 t t as i di t d t 25, and unlocking of t e s pa ab e pa and the rear end being slightly extended between It is an additional Object of my inve t to the sides at the hinged portion as indicated at provide a construction that is made up of easily as see Fig 7 for th pu pgse hereinaftgr manufactured parts, readily assembled together, b d 20 whereby the cost of manufacture is reduced. Referring now to Fig. 6, the clamp member With. the above and other objects and advan- 53a, of the rear section it is similar to the clamp a e us features in View, y invention Consists member is of the front section it, the spring of a novel arrang me 01" parts more fully tongue it being hinged at the forward end thereclosed in the detailed description following, in of between the sides l'la, by means of a hinge pin 25 conjunction with the accompanying drawing, and 7; the top is Cut back, and the tongue 5 has more Specifically defined in the claims app its rear end rolled to provide an end roll 28, thereto. and is bent as illustrated, with a spring lug 29 In the drawing, out out of the upper stock and extending above 30 Fi 1 is a p plan View of the novel its surface to function as a spring latch in con- 30 nection; nection with the forward edge of the opening Fig. 2 is a bottom view thereof; it, the end of the tongue being reduced in width 3 5 a central longitudinal section thereo and shaped as indicated at 33 to serve as a Fig. is a perspective view, partly broken fingerpmssure element aw y, the relative position of the Oper The clamp members l3 and l3a each have 35 ating parts; mounted therein a bracelet lock cam 3 i see Figs. F g. 5 s a perspective View of one Sectlon; 3 and 4, comprising a forward element 32 hing- Fig. 6 is a perspective view of the cooperating edly secured between the respective sides of the section; members and a rear cam element 33 which exg- 7 is a Perspective w Of 6116 cover p tends upwardly when in locking position and 40 and has edge recesses 34 for snapping engagement Fig, 8 is a perspective view of the housing porwith projections 35 on the sides of the members tion of the first section. 7 l3 and its, the ends of the elements 32 being Referring to th draw n he n v l r p c nshaped, as by providing teeth Or the like, to firmly nection it comprises a section it and a second grip a strap or bracelet end and to retain the 45 section E? which is detachably securable thsrssame within the members is and iZ-la. to, the Sect on N including a Clamp member Referring now to Figs. 5 and 6, illustrating the a hou 94 d a Cover plate and the two end connection sections separated but in t o 52 including a Clamp member 33a and a relative attaching position, the section l2 may be spring tongue element it which is adapted to be moved forwardly to insert the tongue it into 50 detachably received in the housing Hi. All the the housing until the spring latch 29 snaps parts are preferably made of sheet metal stamped upwardly into locking engagement with the front into the form illustrated. edge of the opening 2 l the cover I5 is then swung The clamp member l3, see Fig. 5, is formed downwardly until the recesses 25 fit over the roll 55 U-shaped, with the sides slightly tapered and 28, and the end 2'2 snaps thereover, whereby 55 the parts are thus doubly locked against separation, first because of the. spring latch engagement of the tonguein the housing, and second, because the cover locks over the roll To separate the parts, the cover 5 5 is first lifted by means of the finger tab 23, the end 26 of the cover engaging the forward edge SZof the lower portion of the housing, see Fig. 8, which. serves as a limit stop for preventing excessive swinging move- Inent of the cover, and the finger element 3%} is then depressed to disengage the latch is and permit separation of the sections? It is thus evident that the novel invention is made up of very simple elements, readily manufactured out of stamped metal and easily assembled together, the construction providing a positive lock against accidental separation of the parts, and yet permitting easy separation when desired. Although the invention has been described as applied to wrist watch straps, it may 20 be used for ,bracelets and other articles which. are detachably securable together.
While I have described a specific constructional embodiment of my invention, desired changes in the shape, material, relative size, and relative ,,proportions of the parts may be made to suit "the requirements for different uses, without departing from the spirit and scope of the invention as defined in the appended claims.
I claim: 7 "1. In a detachable connection, a section having a housing, said housing having a catch opening, a
cover pivoted to said section andextending over said housing, the free end of said cover being rounded, a second section having a spring tongue, one end of said second section forming a roll, said spring tongue having latch projecting therefrom, said latch extending into said catch opening and said cover detachably engaging said roll when said spring tongue is seated in said housing.
2. In a detachable connection, a section having a housing, said housing having a catch opening, a second section having a spring tongue, one end of said second section forming a roll, said spring tongue having a latch projecting therefrom and adapted to extend into said catch opening when said spring tongue is seated in said housing, said first section ha Lng a pivoted closure element, the free end of said element being detachably engageable with said roll when said spring tongue is seated in said housing.
