Description
SNAP STUD
DescriRtion Technical Field - This invention pertains to a snap stud particularly for use in window hardware for releasably pivotally interconnecting two members. The snap stud is constructed to facilitate assembly of the window hardware by use of automatic equipment and to releasably retain the window hardware members in pivotally inter-connected relation whereby the members may be separatedfor movement of a window free of restraint by the window hardware.
Background Art There are many different types of window hard-ware having pivotally interconnected members. One type is a window operator having an operating arm connected to a bracket mounted to a window sash. A releasable connection is achieved by the use of a slidable keeper member on the operating arm which, in one posi-tion, interfits with a stud on the bracket to lock the parts together in a pivotally interconnected relation. A
slidable keeper of this type is shown in Armstrong U.S.
Patent No. 3,~57,675.
Another type of window hardware is a window hinge. A sash arm is pivotally attached to a slider or shoe movable along a guide track fixed to a window sill and a support arm or link extends between the guide track and the sash arm and is pivotally connected to both~
A commercial embod~ment of a window hinge utilizes a keeper and stud structure of the type shown in the ~d`~
8~
referred to Armstrong patent for releasably connecting the support arm to the guide track. In assembly, the sash arm must be manually oriented with the end adapted for mounting the keeper positioned adjacent the guide track and the keeper must be manually handled.
The present commercial window hardware using a slidably mounted keeper is not readily assembled by use of automatic equipment because of the required handling of the keeper and orientation of the hardware elements.
Disclosure of the Invention A primary feature of the invention is to provide a snap stud for releasably holding a pair of members, such as components of window hardware, in pivotally inter-connected relation and which avoids the need for a slidably mounted keeper with resulting cost reduction and the ability to perform part of the assembly of the window hardware on automatic equipment because of ease of handling and orientation of components. The snap stud enables separation and assembly of the members relative to each other to be accomplished without tools and the snap stud emits a positive "snap" sound when returning to its retention position, thereby signalling proper interconnection of the members to each other.
The snap stud replaces the slidable keeper used in the prior commercial window hardware structures and thus avoids a number of problems encountered in the use o~ a keeper, including special orientation of the member which is to mount the keeper, difficulty in manufacturing the keeper, the inability to automatically manipulate the keeper in assembly processes as well as possible damage thereto during assembly.
Additionally, the snap stud is not readily apparent as constituting a releasable connection between the members and, therefore, the window hardware is more tamper-proof than when a keeper is used which is readily visible as being a member which, when moved, will disconnect the two members and permit movement of a window sash independently of the window hardware. Further, the use of the snap stud in place of the stud and keeper of the prior art results in a cost savings of approximately 1/3 in the cost of the parts.
Generally, the invention seeks to provide a snap stud for mounting on a first member and releasably holding a second member in pivotal relation with the first member comprising a generally cylindrical portion having an external peripheral groove intermediate the ends of the portion. A C-ring of spring wire is positioned in the peripheral groove and has a pair of spaced-apart ends, the C-ring having inner and outer diameters selected to have a part thereof in the peripheral groove and a part extending beyond the periphery of the cylindrical portion when the C-ring is in a retention position. The peripheral groove has a depth to enable compression of the C-ring to a release position in which substantially all of the C-ring is in the peripheral groove.
More particularly, one embodiment of the invention pertalns to a releasable connection means for window hardware which comprises a snap stud including a generally cylindrical portion having an outer periphery, a first window hardware member and means attaching the cylindrical portion to the first member so that the cylindrical portion and the first member are fixed against relative movement axially of the cylindrical portion. A second window hardware member has a through opening, the cylindrical portion extending through the opening so that the first and second window hardware members are pivotable with respect to each other. The cylindrical portion has an external peripheral groove intermediate the ends of the cylindrical portion and a C-ring of spring wire defining a generally circular centerline is positioned in the peripheral groove and has a pair of spaced-apart ends. The C-ring has inner and outer diameters selected to have a part thereof in the peripheral groove and a part extending beyond the outer periphery of the cylindrical por-tion when the C-ring is in a retention position. The diameter of at least a 86~.
portion of the through opening of the second member is less than the outer diameter of the C-ring and is greater than the diameter of the csnterline of the C-ring when the C-ring is in the retention position~ The peripheral groove has a depth to enable compression of the C-ring to a release position in which substantially all of the C-ring is in the peripheral groove and which enables disassembly of the first and second members by pulling one member away from the other a~ially of the stud.
Other aspects and embodiments of the invention will become apparent from the more detailed description of the invention herein.
Brief Descri~tion of the Drawings Fig. 1 is a perspective view of a window hinge utilizing the snap stud;
Fig. 2 is a fragmentary vertical section, taken generally along the line 2 - 2 in Fig. l;
Fig. 3 is a plan section, taken generally along the line 3 - 3 in Fig. 2; and Fig. 4 is a view, similar to Fig. 2, showing the snap stud action that occurs during an assembly operation.
Best Mode for Carrying Out The Inventlon As previously mentioned, there are different types of window hardware which have releasable pivotally interconnected members including window operators and window hinges. The snap stud embodying the invention is shown in association with a window hinge and it will be understood that the snap stud also has utility in a window operator.
The window hinge, indicated generally at 10, mounts a window sash (not shown).
The window hinge has a guide track 22 mountable to the sill of a window frame. A sash arm 23 fastens to the underside of a window sash and at one ~2 ~ ~6l~
end is pivoted at 24 to a slider or shoe 25 which is movably mounted in the guide track 22. A support arm 26 has one end pivotally connected at 27 to the sash arm 23 and at it~ other end 28 is pivotally connected to the guide trac~ 22 by a snap stud, indicated generally at 30.
The snap stud 30 functions to releasably retain the support arm and the ~uide track in pivotally interconnected relation.
I The snap stud is shown more particulàrly in Figs. 2-4. The snap stud com~rises a cylindrical portion or stud 40 which extends from the guide track 22 and is fixed thereto. The stud has a tubular lower part 42 of reduced diameter extending through an opening 44 in the guide track 22 and pressed outwardly to form a rim 46. The guide track 22 is captured between a flange 48 on the stud and the rim 46.
The stud 40 has a stud section 50 with an external peripheral groove 52 defining a neck adjacent a head 54 at the free end of the stud. A C-ring 60 of round spring music wire is posi~ioned in the external peripheral groove 52. The C-ring i8 partially circular and has an inner diameter less than the diameter of the stud 40 and an outer diameter larger than the stud 40.
As seen in Figs. 2 and 3, the C-ring has a retention position wherein part of the spring is within the ex-ternal peripheral groove 52 and part thereof extends beyond the periphery of the stud 40. The C-ring has spaced-apart ends 62 and 64 which are spaced apart less than the diameter of the stud base section 50 whereby the C-ring must be forced into position in the exter-nal peripheral groove 52 in assembly and, thereafter, ~,'.,~ ' ~2~3fil.
is retained in assembled relation. The external periph-eral groove 52 has a depth approximately equal to the diameter of the spring music wire.
The action of the snap stud in releasably retaining the window hardware members in pivotally interconnected relation is best seen in Fig. 2. The external peripheral groove 52 is at a distance from the stud flange 48 at least equal to the thickness of the support arm, and the C-ring 60 is in its retention position and overlies the end 28 of the support arm.
The support arm has an opening 70 to receive the snap stud which is of a diameter less than the outer diarneter of the C-ring when the latter is in its re-tention position. In assembly or disassembly of the window hardware members relative to each other, the C-ring 60 is compressed by the support arm 26 to a position where it lies substantially entirely within the external peripheral groove 52, as illustrated in Fig. 4, whereby the support arm can move to and ; 20 from its associated position with the guide track 22.
The action of the support arm in compressing the C-ring 60 is facilitated by the camming action derived from the roundness of the wire used in forming the C-ring.
From the foregoing, it will be evident that two window hardware members can be releasably pivotally interconnected merely by forcing the stud 40 into the opening 70 of the support arm 26 with automatic com-pression of the C-ring 60 and, aftçr the members are assembled into the position shown in FigO 2, the C-ring returns to a retention position to maintain themembers in assembled relation. The snap stud emits a !
~L2~
positive "snap" sound when the parts reach the assembled position shown in Fig. 2, thus signalling proper interconn~ction of the members.
When the snap stud is used to pivotally interconnect a support arm of a window hinge to a track associated with the windo~ sash, it is possible to utilize a simplified support arm having openings of the same size adjacent each end thereof, with one opening being used for the pivot connection to the sash arm and the other for association with the snap stud. This simplification of the support arm in not requiring a mounting for a slidable keeper facilitates the automatic assembly of the window hinge by avoiding the necessity for orienting one particular end of the support arm in a particular position.
The snap stud can be used in a window operator of the type shown in Van Klompenburg U.S. Patent No. 4,241,541 to pivotally interconnect the ~onnecting link 41 and the bracket 42.
