ONE-PIECE MOLDABLE CAMERA SOCKET FOR DETACHABLY HOLDING A MULTILAMP PHOTOFLASH PACKAGE Filed July 12, 1965 PA UL J- ERNISSE INVENTOR.

ATTORNEYS United States Patent 3,407,717 ONE-PIECE MOLDABLE CAMERA SOCKET FOR DETACHABLY HOLDING A MULTI- LAMP PHOTOFLASH PACKAGE Paul J. Ernisse, Rochester, N.Y., assignor to Eastman Kodak Company, Rochester, N.Y., a corporation of New Jersey Filed July 12, 1965, Ser. No. 471,182 9 Claims. (Cl. 95-11) ABSTRACT OF THE DISCLOSURE A multilamp photoflash socket having a base, a control ring with indexing notches for cooperating with the camera indexing mechanism, a plurality of upwardly ex tending flexible retaining fingers for engaging the retaining lugs extending downwardly from the connecting base of the multilamp package, and a cylindrical outer wall having a plurality of radially inwardly extending ribs the top surfaces of which define an access opening into the socket to aid insertion of the multilamp package.

This invention relates to flash photography, and more particularly, to socket arrangements for receiving multilamp photoflash packages.

There has recently been developed a disposable multilamp photoflash package disclosed, for example, in US. applications Ser. No. 417,913, now Patent No. 3,353,465, and 417,914, now Patent No. 3,327,105, both filed Dec. 14, 1964. Such a package includes an attaching platform on which are mounted a plurality of photoflash lamps and individual reflectors. My invention comprises a one-piece socket, which may be used in a suitable flash device, to detachably receive and retain these packages.

A primary object of my invention resides, therefore, in the provision of one-piece multilarnp package receiving socket for use in a suitable fiash device.

This and other objects and advantages will become more apparent during the course of the following description, the accompanying drawing forming a part thereof and wherein:

FIG. 1 is a plan view of a preferred embodiment of a one piece socket according to my invention; and

FIG. 2 is a cross sectional view taken on line 2-2 of FIG. 1, showing the socket with a multilamp package attached.

Referring to the drawing, a one-piece multilamp receiving socket 10 comprises an annular body portion 12 including four ribs extending inwardly therefrom, the top surface 13 of which defines a central access opening 14 in the shape shown. An integral base 15 at the lower end of body 12 defines an upwardly extending stabilizing stud 16.

Also extending upwardly from base 15 are a plurality of resilient retaining fingers 17 having engaging projections 18 defining upper cam surfaces 19 and lower latch surfaces 20.

The socket 10 may also include a suitable control ring 23 with indexing notches 24 to control the position of the socket by an indexing mechanism. A suitable indexing mechanism in a photographic still camera is shown in US. application Ser. No. 458,015, now Patent No. 3,353,467, filed May 24, 1965. As is also disclosed in that application, the central stabilizing stud 16 may define a slot 26 through which an ejector pin may pass to provide for selective ejection of an inserted lamp package.

The lamp package as described in the above applications Ser. No. 417,913 and 417,914 includes a base 30 and a depending connecting post 31 of cylindrical shape which is placed over the stabilizing stud 16 When inserted into the access opening 14. The post 31 includes at its lower 3,407,717 Patented Oct. 29, 1968 end four retaining lugs 32 extending radially outwardly and having upper and lower ramp surfaces.

As a lamp package is attached by inserting the post 31 into the central access opening 14, the lower ramped surface of each lug 32 engages the cam surface .19 of a respective finger projection 18 to move the finger laterally outwardly against its bias. As the package is fully seated, the fingers spring back until the latch surfaces 20 engage the upper ramped surfaces of the lugs 32 to retain the package as shown in FIG. 2. Removal of the package from the socket by pushing with an ejector pin at the lower edge of post 31, or by pulling the package out, causes the upper ramped surfaces of lugs 32 to again move fingers 17 outwardly until they are clear of the lugs 32.

An important aspect of my invention is that the socket and package retaining means is in one piece, which may be formed by molding. A suitable material from which to mold the socket 10 is a polycarbonate plastic, although any material having sufiicient elastic resiliency to form the fingers 17 may be used.

While my invention has been described with reference to a preferred embodiment, it is obvious that variations can be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

I claim:

1. A one-piece molded socket adapted to detachably hold a multilamp photoflash package comprising:

a base adapted for mounting on a camera;

a plurality of flexible, retaining fingers, extending upwardly from said base, each of said fingers terminating in an enlarged projection defining an upper cam surface and 'a lower latch surface; and

a central stabilizing stud.

2. The apparatus according to claim 1 wherein said st-ud is hollow and defines an ejector slot extending through the wall thereof for receiving an ejector pin of the camera for use in detaching the multilamp photoflash package from said socket; and including a control ring extending radially outwardly of said base and defining a plurality of notches therein adapted for operative engagement with an indexing mechanism of the camera.

3. The apparatus according to claim 1 including:

a substantially cylindrical outer wall extending upwardly from said base, radially outwardly of said fingers, said wall having a height greater than that of said fingers and less than that of said stud, and

a plurality of ribs extending radially inwardly from said wall and terminating short of said stud, said ribs being interleaved with said fingers, the top surface of said ribs defining an access opening into said socket for said package.

4. A one-piece molded socket for detachably holding a multila'mp photoflash package, comprising:

a body member adapted to receive a multilamp photofiash package;

a plurality of flexible retaining fingers extending from said body member and positioned so as to engage retaining lugs on a multilaimp photoflash package insorted into the socket, each of said fingers including a projection having upper and lower ramped surfaces; and

a stabilizing stud extending from said body member and adapted to engage a downwardly extending post on a multilamp photoflash package inserted into the socket.

5. A one-piece molded camera socket for detachably retaining a multilamp photoflash package of the type having a base including a downwardly extending, hollow center post having a plurality of equally spaced retaining lugs extending radially outwardly from the lower end of the post, said socket comprising:

a base adapted for mounting the socket on a camera;

a plurality of flexible fingers extending upwardly from said base for engaging the lugs of said package, each of said fingers terminating in an enlarged projection defining an upper cam surface and a lower latch surface; and
