6 Claims. (Cl. 248-409) This invention relates to a novel device for supopenings 3, as described more fully hereinafter porting an object, such as a radio coil unit, and (see Figs. 3 and 4). It will be understood that has for its principal object the provision of an the mandrel or support 2, together with the coils efiicient' device of this character which may be I supported thereby, constitute a coil unit, such manufactured and assembled very economically. as may be employed in the conventional multi 5 While the invention is capable of use for supband radio receiver. porting objects generally, it is particularly di- The resilient member or yoke 4 is preferably rected to the support of coil units in a modern formed from a strip of flat resilient metal bent to multiband radio receiver, that is, a receiver the shape 'shown in Fig. 3.

In further accordance with the invention, there so The invention may be more clearly understood is pro ed 011 the pp t e I a tab 0 by reference to the accompanying drawing, in tongue 9 S Width that it y be i rted which snugly between the arms 5 of the resilient mem- Fig. 1 is a perspective view illustrating the supber or yoke 4. The tongue 9 may be formed by porting device of the invention; offsetting a portion of the flat base I, as shown 35 Fig. 2 is a sectional view of the same; clearly in Figs. 1 and 2, so that the tongue will Fig. 3 is a perspective view of the resilient yoke be integral with the b There re l o prefemployed in accordance with the invention; erably provided on the tongue 9 an opening I!

The 0 coll unit which may be supported by the device; detent may be formed by striking out and raising 40 and a small portion of the tongue 9. With the coil Fig. 5 is a fragmentary sectional view of amodlunit attached to the resilient yoke l, the tongue flcation. 9 is inserted within the yoke adjacent the end Referring particularly to Figs. 1 and 2, there of the coil support or, in other words, the yoke is shown a portion of a base I which may be is placed over the tongue. The parts are prefformed of sheet metal and which is representative r bly o m n oned h i i n ssary to of any supporting means to which a coil unit may force the tongue 9 between the end of the coil be attached in accordance with the present inpp and the bowed portion 8 st the vention.

It will be apparent, u

of course, that the resilient yoke may be removed from the tongue 8 by raising the bowed portion of the yoke sufilciently to clear the detent ll. When the parts are in assembled relation, as shown in Fig. 2, the resilient bowed portion I of the yoke maintains the end of the coil support 2 in snug engagement with the tongue I, and at the same time, the seating of the bowed portion in the opening it prevents lateral movement of the coil support.

In Fig. 5, there is shown a modification in which the tongue 9a or the support oibase la is offset or depressed, as shown at l2, so as to provide a downwardly projecting circular protuberance over which the end of the mandrel 2 snugly seats. The coil support is thus held firmly in position. The resilient bowed portion oi the yoke 4 extends into the recess at the top of portion l2 and engages the said portion, as clearly shown, thus maintaining the end of the coil support snugly against the tongue 9a. This interlocks the parts together'as will be clearly understood from the preceding description. It will be apparent that the parts of the device may be assembled or disassembled in substantially the same manner as described above.

It will be noted that in both of the embodiments illustrated and above described, the resilience of the arms of the yoke maintains the yoke in interlocked relation with the coil support or mandrel, while the resilience of the bowed portion of the yoke maintains the end of the mandrel in snug engagement with the tab or tongue 9.

It will be seen from the above description that the invention provides a very simple device which may be manufactured and assembled very economically without the necessity oi employing mechanical attachment devices requiring tightening or manipulation and which serves to hold a coil unit firmly in position. It will be understood, of course, that the invention is not limited to the specific forms of the device herein illustrated and described for the purpose of disclosure but that various other modifications of the device may be made within the scope of the invention.
