MOUNTING BRACKET Filed July 1, 1963 3 Sheets-Sheet 3 INVENTOR. WILSON u. A7027??? United States Patent 3,158,343 MOUNTING BRACKET Wilson .I. Rutter, 11%11 28th SW., Seattle, Wash. Filed July 1, 1963, Ser. No. 291,775 17 (Jlaims. (Cl. 24824-0.4)
The device of this invention is intended as a bracket whereby various articles may be mounted, temporarily or permanently, upon a support such as a wall stud. The device should be made of a size to fit a specific size of support, but could be made to fit a 2 x 4 wall stud, a 4 x 12 floor joist or roof joist, or any other similar support, verticaly or horizontally disposed. The support should be of wood or like material, for a dog or bit, or a pair thereof, is or are designed to pierce the side or sides of the support to insure against the bracket being pulled off.
In essence the mounting bracket comprises a channelshaped body of a size to straddle the support and to lie close to its opposite sides. A dog or bit at one side, or two bits at the opposite sides, is or are directed inwardly towards the side surface or surfaces of the support. While one such bit might suflice, two are shown and preferred, and two will be referred to hereinafter, it being understood that the use of one only is not outside the scope of the invention. These bits are held outwardly from the surfaces towards which they are directed by their immediate support, and since it will usually be desirable for purposes of initial installation and later withdrawal of the bracket from its support, the immediate support for the bits preferably takes the form of resilient elements upon which the bits are secured or formed. Movement of the bits towards and into the wood of the support, in opposition to the resilience of the resilient elements, is accomplished by cam means including an operating lever pivotally mounted upon the channel-shaped body and cooperable with camming surfaces operatively associated with the resilient elements to urge them inwardly, or by reverse movement permitting (or in certain possible embodiments, causing positively) the resilient elements to withdraw the bits. As stated, the cam means referred to includes a level pivotally mounted upon the channel-shaped body, and when parts are in position with the bits piercing the support, this lever is in position to support a plank as a scaffold or shelf panel, or to perform any desired supporting function. Stop means on the channel-shaped body or on the resilient elements, when engaged by the lever, prevents further swinging of the lever, and strongly supports the same. The pivotal support for the lever may be of a type permitting its disengagement from the body, for ease and compactness of packaging and storage, yet such that accidental disengagement is unlikely. In preferred forms the bits are projected into the wooden support through apertures in the channel-shaped body, whereby these bits are strongly reinforced to resist any tendency for them to bend or break loose. The bits may take various forms, as also can the resilient members.
The general object of this invention is to provide a mounting bracket having the general form and capability indicated, which can be made easily and inexpensively, and which will be simple yet rugged in construction, and which can be applied, and if need be removed, in a simple and expeditious manner, and which when applied will hold tenaciously to its support until released.
It is also an object to providesuch a mounting bracket capable of application not only to upright wall studs but to horizontal or inclined supports such as floor or ceiling joists or the like.
Also it is an object to provide such a device wherein the bracket may mount or support various types, shapes,

or sizes of supported articles, when designed for the support of any particular article, or may support two or more different articles.
Further objects and advantages will appear as this specification proceeds.
In the accompanying drawings, the invention is shown as embodied in several variant forms. The drawings also illustrate the mounting bracket as supported from a wall stud, and it will be obvious how it could be modified or used for support from a different member.
FIGURE 1 is an isometric view of a form which is presently preferred by me, in the position of use, and FIGURE 2 is a side elevational view of the same, illustrating other positions in dot-dash lines.
FIGURE 3 is a view similar to FIGURE 2, showing the device in an elongated form.
FIGURE 4 is a view similar to FIGURE 1, but showing a modified form in position for application to or removal from a stud, and FIGURE Sis a view of the modified form, corresponding to FIGURE 2.
FIGURE 6 is an isometric view of the channel-shaped body, in another modified form, and FIGURE 7 is an edge view of one side of this form, in position of use.
FIGURE 8 is an isometric view of a still further form of the channel-shaped body, and FIGURE 9 is a plan view of the same form, in position of use.
To illustrate the invention it is shown as designed for application to an upright wall stud S, of 2 X 4 size, for the purpose of supporting a plank P to form a scaffold. However even in this design it may be readily and usefully mounted upon a rafter, beam or other member regardless of orientation and for a wide variety of uses.
It comprises a channel-shaped body 1 of a size and shape to straddle one edge of the stud, with its side plates 10 closely embracing the opposite side surfaces of the stud. Its base portion 11 rests against one edge of the stud. It may be of any suitable length; in all figures except FIGURE 3 it is short, but in FIGURE 3 is of rather appreciable length.
Projecting inwardly from one or from both of the side plates or flanges 10 are dogs or bits 2. Two opposite bits are shown in each form. They are movable inwardly and outwardly with respect to the side plates 10, and can be supported from the latter by means such as resilient fingers 20 (FIGURES l, 2, and 3) which are secured by their lower ends, at 21, to the side plates 10, and extend thence upwardly and outwardly when unstressed, to the end that the bits 2 are normally withdrawn from the stud S. The side plates 10 are desirably apertured so that the bits may pass through freely, a hole 12 being shown for the purpose, but each such aperture closely embraces the bit when the latter has pierced the stud, and thereby strongly reinforces the bit and it may also be designed to have the eiiect of presenting a bearing surface to the wood immediately surrounding the bit in order to resist outward deflection of wood fibers attending tearingof the bit across the grain when under load. To this extent the wood also is reinforced in order to withstand greater loads.
In order to move the bits 2 inwardly, to pierce the stud, a oammiing action occurs between the upwardly and outwardly inclined resilient fingers Ztl and arms which lie at one side of the transverse pivot pin 31 of a lever 3, the larger and supporting portion whereof extends oppositely from the arms 30. These arms 3d lie outside the fingers 29, and rather close to the exterior surface of the side plates It), so that when the lever and its arms 39 swing from the dot-dash line position of use, the arms 3t) will crowd the fingers 20 and their bits 2 inwardly, to pierce the wooden stud which the channelshaped body 1 straddles.
The pivotal mount of the lever .3 upon the body 1 may vary in form, and may be permanent or releasable. Preferably it is of the latter type. To this end a strap ll) is secured to the base 11 of the channel-shaped body, and its upper end is bent outwardly at 4, and upwardly, to form a groove to receive the pivot pin 31 when the latter is moved downwardly; see the double-dot-dash line in FIGURE 2. Obviously, the pivot grove may be otherwise formed, and different forms are shown in the other modifications illustrated.
Swinging movement of. the lever should be stopped in a precise position, in order that the same may constitute a rigid support. Stop means may be mounted directly upon the body I, or indirectly upon the fingers 29, as shown. The stops 22 are conveniently formed by hanging outwardly the upper ends of spring fingers 20, in such position relative to the pivot groove at d that upward swinging of the arms 30 is stopped when the lever 3 is horizontal, or in any other desired position. Thus, as in FIGURES l and 2, when horizontal the lever 3 will support a plank P or other such element. A retainer 32 engages the outer edge of the plank to prevent its sliding oil. Note that any load upon the plank acts downwardly against the upwardly opening pivot groove 4 and upwardly against the downwardly facing stops 22. There is little likelihood that the lever can be accidentally dislodged. This arrangement facilitates shipment and storage of the body 1 and the lever 3 in separated condition, yet they are readily engaged.
In FIGURE 3 the body 1 has been shown greatly elongated, and instead of supporting the plank P upon the lever 3, a supplemental lever 33 is pivoted upon the body I, and braced therefrom by the brace chain 34. The lever 3 may be used as a hanger for a bucket of paint, or other article, as an auxiliary support.
The form shown in FIGURES 4 and 5 is quite similar to that already described. Here the pivot groove 4a opens laterally to receive the pivot pin 31, but the arms 3b are formed at their swinging ends with retainer fingers 34 which embrace the edge of arcuate spring-fingers 20a, formed concentrically of the pivot axis. This precludes accidental disengagement of the lever 3 from the body 1, until parts are in the two-dot-dash line position of FIGURE 5. In this form the bits 2a are shown as tabs struck from the metal of the fingers 29a, and the latter as struck from the metal of the side plates Ill.
In the form of FIGURES 6 and 7 the spring fingers 2% are struck from metal of the side plates 1%, bent directly upwardly and inclined outwardly when relaxed. They are urged inwardly by the camming action of arms 39, as in FIGURE 7. This presses inwardly the bits 25, shown as struck from the metal of the fingers 291). In this form the bits 2b are closely embraced by the edges of recess 1252 (FIGURE 6), of notch formation, and thereby the bits are strongly supported by the edge of this recess 1211 against the stress to which they are subjected in use. This form also shows a slight change in the pivot groove 4b, which now is struck from the metal of the base portion 11 of the channel-shaped body 1.
In the form shown in FIGURES 8 and 9 no separate spring. fingers are provided, but instead the side plates Ills diverge slightly away from the base 11 of the body 1, and at their edges distant from that base are flanged laterally, at 13, and the edges 14 of such flanges are inclined upwardly and outwardly. The entire side plates, with these flanges, constitute resilient spring fingers or elements, and are urged inwardly by the camming action of upwardly swinging arms 3%; compare the dot-dash line and full line showings of FIGURE 9. By striking bits 20 from the metal of the side plates, so that they are directed inwardly when the flanges 13 are bent, they will bite into the stud S when the side plates are thus urged inwardly. The pivot groove 4b is formed in the same manner as in FIGURES 6 and 7. Stops 220 are also formed at the l upper'end of flanges 13, for engagement with arms 30.
In the form of FIGURES 4 and 5 a supplemental support such as the hook I5 is shown. This may afford a convenient support for a paint bucket. mental supports may be provided in other forms, and in various location.
