2 Claims.

This invention relates to a structurally and functionally improved receptacle and in its more specific aspects aims to provide a unit of this character which is intended for cooperation with a rotatable unit such as a stud for the purpose of providing a readily operable fastener assembly.

It is an object of the invention to design a unit of this type and the parts of which will be somewhat self-centering or adjusting. Accordingly, when associated with a mounting sheet or similar element, a certain latitude or alignment is permissible. Accordingly, not alone is the time and effort necessary to mount the fastener reduced, out also the cooperation of the receptacle with the second part of the'fastener assembly will be materially expedited.

'A further object is that of designing a receptacle which will preferably embody a certain amount of resiliency, Accordingly, extraneous springs or functionally corresponding structures may be reduced or completely eliminated in the case of certain designs of fastener assemblies.

Still another object is that of providing a receptacle and mounting therefor and which may be combined in a manner such that they may readily be shipped and handled as a unit by the ultimate user. Thus, this user will not have to unnecessarily assemble several parts to provide the complete receptacle.

An additional object is that of furnishing a structure as enumerated in the foregoing paragraph and which will include relatively few parts, each individually simple and rugged in construction, these parts being largely capable of manufacture by automatic methods and machinery and when combined furnishing a unitary structure operating over long periods of time with freedom from all difficulties.

With these and other objects in mind, reference is had to the attached sheet of drawings illustrating one practical embodiment of the invention, and in which:

Fig. l is a sectional side view of a receptacle and showing the same mounted;

Fig. 2 is a plan view thereof with certain of the parts in a section taken'along the lines 2-2 and in the direction of the arrows as indicated in Fig. l; and

Fig. 3 is a transverse sectional view taken along the lines 33 and in the direction of the arrows as indicated in Fig. 2.

In these views, the reference numeral 5 indicates a plate which may be of oblong configuration and provided with a central aperture 6. This plate is preferably formed of material having inherent resiliency such as steel and the side edges of the plate may be turned upwardly as indicated at l to provide flanges. The latter serve to some extent to rigidify the plate and prevent undue flexing of the same.

According to the embodiment illustrated, this plate provides a receptacle for cooperation with a stud assembly which may include a worm member 8. The details of the latter have not been shown. Suffice it to say that it generally includes a rotatable stud mounting a structure suitable for cooperation with the particular design of receptacle or receiving element. Incident to this cooperation and with the stud carried by one sheet or unit and the receptacle carried by a second sheet or unit, it is feasible to readily couple the sheets or their equivalents. Such a result is preferably achieved by effecting relative rotation of the parts in one direction. A detachment of the parts of the fastener may be achieved by a reverse rotation of the parts, Any suitable structure or structures may be combined with the stud to retard or prevent accidental rotation of the latter. The foregoing is, therefore, to be considered in an illustrative rather than a limiting sense.

However, if a fastener employing a worm bread is utilized, then the receptacle is conveniently formed with a pair of inwardly extending and opposed lugs 9. These cooperate individually with the convolutions of a double thread for-med on the stud. Accordingly, as the latter is 1'0- tated with respect to the receptacle, such receptacle is caused to move axially with respect to the stud. Therefore, the sheets or other mounting members with which the stud and receptacle are respectively associated. will be drawn towards each other. If a structure other than the worm 8 is associated with the stud, then any proper and desired structure may be substituted for the lugs 9 of the receptacle.

The receptacle is preferably to be fioatingly supported with respect to the member mounting the same. With a view to achieving this, that member which, in the embodiment illustrated, is in the form of a sheet Ill, has an aperture l! with which the aperture 6 is to be substantially aligned. Moreover, the mounting member or sheet I6 is conveniently formed with openings which may receive rivets 12. Obviously, these rivets might take numerous diiferent forms from the one herein illustrated. Also, any other and substitute form of mounting element might be employed for cooperation with the parts of the receptacle assembly and to secure the latter to the sheet.

Considering that assembly, it will be observed that it conveniently includes a pair of collars or mounting members l3 or members suitably bored to accommodate the elements which fasten the assembly to the mounting member. These members [3 are preferably of one-piece construction as illustrated. They are formed with reduced parts or grooves 14 at a distance properly spaced from the base portions thereof. The ends of the plate 5 are notched as indicated at l5 and define preferably circular recesses having diameters in excess of the base of the grooves H but less than the diameter of the collar or members IS. The outer ends of these recesses are defined by inwardly extending lips or projections 15. These are spaced to an extent slightly less than the diameter of the grooves 14. Accordingly, while the plate 5 may shift with reference to the collars I3, it will not accidentally detach therefrom.

Thus, it follows that the assembly includes the receptacle proper which comprises the plate and its associated parts as well as the collars l3. The latter are disposed in proper relationship with respect to the receptacle by simply aligning the grooves M with the projections I 6 and then forcing the collars inwardly into the recesses or notches 5. The parts will spring to an extent suflicient to permit of this. However, a subsequent accidental detachment of the collars from the plate will not occur.

With the collars coupled to the mounting memher in any suitable manner, it is thus apparent that the receptacle may be shifted laterally. This will permit its aperture 5 to align with the aperture H, Such shifting will occur automatically and without any conscious effort on the part of the operator because, ordinarily, the stud cooperating with the receptacle will have a structure such that the parts will be guided as they come into contact. Due to the resiliency of the plate 5, the latter will flex as the stud is rotated to a point at which the receptacle is tensioned. This will be true whether a worm such as 6 or any functionally equivalent structure is employed. Obviously, under these circumstances, the surfaces of the plate 5 will firmly engage the adjacent surfaces of the grooves I l and there will be no further tendency of the parts to shift. Thus, all units of the assembly will, in effect, present a unitary and non-shifting structure.

The function or lateral shifting or adjustment is especially important where a group of fastener assemblies are associated with sheets or other mounting members. It is obvious in bringing the latter together that, due to inaccuracies in locating the parts of the different assemblies that warpage of the mounting member would normally occur, were no compensating or adjusting structure present. With a structure such as the one herein illustrated or its functional equivalent, all difiiculties in this connection are overcome and no warpage of the sheets nor binding or seizing of the fastener parts results.

Also, as a consequence of the resiliency forming a part of the present receptacle, the stud member will be somewhat yieldingly supported. It is found that as a result of the inclusion of such structure the tendency of the sheets or plates to crack especially adjacent the apertures formed therein is overcome. Moreover, the plates or sheets with which the fastener parts are associated may be maintained in proper face-to-face contact as a consequence of this construction. This is particularly true because-regardless of the detailed structure of the stud member employed-the latter may be tightened to a proper degree and so that its mounting member as Well as the mounting member for the receptacle are properly disposed with respect to each other. Thereupon, any looking or detent structure which may form a part of the assemblies may be permitted or caused to function. In other words, and, as a result of the resiliency present, the proper disposition of the mounting members with respect to each other need not be disturbed as would be the case where such relationship was established and the stud thereupon had to be slightly loosened to permit of an operation of any suitable looking or detent mechanism.

From the foregoing, it will be appreciated that among others the several objects of the invention as specifically aforenoted are achieved. Obviously, numerous changes in construction and rearrangements of the parts might be resorted to without departing from the spirit of the invention as defined by the claims.
