ABSTRACT:
A connector for connecting a base and column of a microphone stand or the like. The connector comprises a cylindric male member having a first end portion adapted for connection to the column and a second end portion having an external annular groove therein. A retaining spring carried in the groove is compressible from an expanded configuration wherein it projects partially out of the groove to a compressed configuration wherein it lies entirely within the groove. The connector further includes a female member adapted for connection to the base of the microphone stand. The female member has a bore therethrough sized to receive the second end portion of the male member with relatively minimal clearance. The length of the bore is only slightly less than the distance the groove is spaced from the first end portion of the male member. Therefore, when the second end portion of the male member is inserted into one end of the bore through the female member, the retaining spring is adapted to move to its compressed configuration, permitting passage of the male member into the bore to a locking position wherein the second end portion of the male member projects endwise beyond the other end of the bore. The retaining spring is adapted to spring outwardly to its expanded configuration when the male member is in its locking position, wherein it is adapted for engagement with the female member to retain the male member therein, thereby securing the column to the base. The male member can be withdrawn from the female member, thereby detaching the column from the base, by exerting an axial withdrawing force on the column sufficient to compress the retaining spring to its compressed configuration. The connector is designed for preventing relative rotation between the male and female members when the male member is in the locking position.
