17 Claims.

The present invention relates to strand-retainers and the like, and more particularly to retainers for holding a plurality of strands, for example electrical conductors, in secure grouped relationship, and aims generally to improve and simplify the construction of existing devices for that purpose.

Among the primary objects of the invention is the provision of an improved retainer readily formed from a single piece of sheet metal and which may be mounted in snap fastener engagement with an apertured support.

Illustrative of theinvention, reference is made to the accompanying drawing showing a preferred embodiment of the invention, and in which Fig. 1 is a top plan view of a strand or-wire retainer according to the invention;

Fig. 2 is an edge elevation illustrating the retainer mounted on a support;

Fig. 3 is a side elevation of the retainer per se;

Fig. 4 is an edge elevation thereof; and

Figs. 5 and 6 are views similar to Fig. 2 i1- lustr'ating alternative modes of grouping a plurality of conductors in the retainer.

Referring to the illustrated embodiment shown in the drawing, the invention comprises a retainer formed with opposed channel-shaped receiving portions separated by a central web, which is provided with integral snapfastener means for attaching the retainer to an apertured support, the web having an elastic band or strap secured thereto for embracing a plurality of strands under tension.

Referring more particularly to the drawing, the retainer may advantageously be formed of a single strip of sheet metal, the opposite end portions of which are shaped to channel form, as at Ill, presenting a web I I and upper and base flanges l2 and II, respectively. The two channel-shaped portions III are preferably connected together by an intermediate strip ll of less width so that the lower flanges I3 may be disposed on opposite sides of the strip It. The strip I4 is bent on itself to provide a nose portion IS with sides connecting the nose and web portions ll, said sides having divergent portions i5 and convergent portions I1 presenting an outward bow or bulge l8 spaced below the flanges 13.

The intermediate or connecting portion thus formed provides a snap fastener means for readily attaching the retainer to a support i which is formed with an aperture 2. As will be apparent from Fig. 2, the nose portion l5 provides a ready means for forcing the snap fastener portion through the aperture of the support, and, when the retainer is in its fully afllxed position, the opposite faces of the support I are engaged by the base flanges l3 and bowed portions 18. Preferably the lower flanges I! are downwardly inclined as shown, so that the ends or feet portions thereof engage the adjacent surface of the support in planes spaced beyond the bowed portions [8, thus providing a tensional ripping effect between the ends and bowed portions.

An elastic strap or band 20 is suitably connected to one of the web portions II and preferably the web portions II are formed with elongated slots 22 through which an end of the band 2|! may be inserted. The other end of the band may be formed with a stop 2| formed in any suitable way. as by a thickened part of the band 20, to prevent the band from being pulled entirely through the slots 22.

The end portions of the upper flanges may be formed with suitable fastening means for the band, and conveniently these fastening means 23 may be in the form of open-sided or T-slots into which an intermediate part of the stretched band 20 may be hooked.

In use, the retainer is snapped into position on an apertured support, as above described, and the elastic band 20 is drawn through the slot 22 until the stop. engages the opposite webs II. A group of strands, such as electrical conductors, may be assembled in one of the channels it and the elastic band thus stretched and extended around the group of strands to engage them under tension, A'n intermediate portion of the band may be hooked'in each of the T-slots, as shown in Figs. 2 and 6, or may be passed around the end of the upper flange l 2 of the receiving channel and hooked into the opposite slot 23, as shown in Fig. 6.

The upper flanges I! may be upwardly sloping,

so as to present a valley in which an additional group of conductors may be retained as shown in Fig. 6. e

The invention provides an eiiicient retainer of extremely simple construction which will effectively hold one or more separated groups of strands in secure position. It will be clear that the strap is reversible in the web portions 1 I so that a group of strands may be positioned in either channel i0.

While I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby, because the scope of my invention is best defined by the following claims.
