Description
March 19, 1963 v. J. JOHNSON STAGING BRACKET INVENTOR. Vf/Vflfll Jay/v50 FiledwDec. 15, 1961 ATTORNEYS.
United States Patent 3,082,027 STAGING BRACKET Vendell J. Johnson, Princeton, Minn., assignor to Alven Enterprises, Inc., Zimmerman, Minn., a corporation Filed Dec. 15, 1961, Ser. No. 159,582 1 Claim. (Cl. 287-54) V This invention relates to a staging bracket, and has as its primary object the provision of a staging bracket for scaffolding or similar material by means of which legs of a staging frame of different heights may be readily and expeditiously set up and taken down with a minimum of effort and difficulty.
An additional object of the invention is the provision of a staging bracket which may be employed with an A- frame of any desired height as, for example, eight feet, fourteen feet, or twenty feet, to provide horizontal staging platforms in different heights, or which, alternatively, may be used selectively at any one of these or other desired heights.
An additional object of the invention is the provision of a staging bracket which will accommodate two by four staging pieces at a given height regardless of uneven ground, provision being made for the bracket to be suitably clamped on a longer piece at an intermediate point to accommodate a short leg.
A further object of the invention is the provision of a staging bracket of this character which may be readily applied to and removed from staging or scaffolding with a minimum of time, difficulty, and effort.
A still further object of the invention is the provision of a bracket of this type which is sturdy and durable in construction, reliable and efficient in operation, relatively simple and inexpensive to manufacture, and which will readily adapt itself to a wide variety of uses.
Still other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter, and disclosed in the accompanying drawings wherein:
FIGURE 1 is a side elevational view of the staging or scaffolding constructed with the bracket of the instant invention, only one-half of the staging being shown, the opposite half being substantially identical, but reversed.
FIGURE 2 is an end elevational view of the bracket per se.
FIGURE 3 is a top plan view of the bracket of FIG. 2; and
FIGURE 4 is a side elevational view thereof.
Similar reference characters refer to similar parts throughout the several views of the drawing.
Having reference now to the drawings in detail, the bracket of the instant invention is generally indicated at and comprises a central rectangular tubular member or sleeve portion 11 which is preferably dimensioned to receive a horizontally positioned two by six scaffolding support or staging.
A threaded boss 12 at one end of tubular member 1 accommodates a set screw 13, for retention of the two by six in position, and at the opposite end of tubular member 11 on the underside thereof there is provided a boss 14 with a set screw 15 threaded thereinto for further securing a horizontal two by six, as indicatedin FIG. 1 at 16.
One side of rectangular sleeve 11 has secured to the top thereof an inclined angularly disposed sleeve 17 of a size to accommodate a two by four angular upright normally comprising a piece of staging or scaffolding, the sleeve 17 being provided on one side with a boss 18 having a threaded bore for the accommodation of a set screw 19. A similar rectangular sleeve 20 of substantially identicaldimension is angularly disposed on the r 3,082,027 Patented Mar. 19, 1963 ice other side of sleeve 11, and is provided with a boss 21 having an internally threaded bore for the accommodation of a set screw 22.
As best shown in FIG. 3, the two sleeves 17 and 20 are offset relative to each other, so that an upright or portion of an A-frame comprised of a two by four may be inserted in each sleeve, without any intersection of the members at the top of sleeve 11.
It is to be noted that the sleeves 17 and 20 also extend at a slight angle relative to the longitudinal axis of tubular member 11 in a direction away from the supporting building. The angle differs slightly and may for example extend approximately one inch to the running foot for sleeve 17 and of an inch to the running foot for sleeve 20.
In FIG. 3 it will be seen that the set screws 22 and 19, as well as the set screw 13, are all operable from the same end of sleeve member 11, which is preferably on the outer side of a building, so as to render positioning, securing, and removal of the brackets a comparatively simple matter.
One form of assembly employing the brackets 10 is shown in FIG. 1, wherein a vertical upright 25 of, for example, 20 foot'length, is selectively threaded through the left hand tubular member 17 of each of three successive brackets. A relatively short length 26 of, illustratively, slightly in excess of eight feet, is positioned at an angle in the opposite sleeve 20, and secured in position by means of the associated set screw.
A second upright of, for example, a fourteen foot length, as indicated at 27, is positioned through the sleeve 20 of the second bracket 10, while a third upright 28 of twenty foot length extends through the sleeve 20 of the topmost bracket. A firm and secure A-frame for scaffolding in three stages, a lower stage 29, an intermediate stage 30, and an upper stage 31, is thus provided by the extension of a transverse beam 16 through the associated sleeves 11, the transverse member 16 being suitably secured to or rested against the side of a building to which the staging is to be applied.
Obviously, greater lengths may be employed as desired, and any one of the transverse stagings 29, 30, and 31 may be omitted, or a single bracket may be successively used from the top stage down to the second stage and thence to the lowermost stage, or oppositely, from bottom to top, each being laid progressively as the work is finished.
Equally obviously, when the base B for the staging is uneven, any selected leg 25, 26, 27, or 28 may be positioned relative to it associated bracket in such manner as to render that leg effectively shorter or longer in accordance with the conditions of the terrain on which it rests.
It may be pointed out that as best shown in FIG. 1, transverse reinforcing members 32. and 33 extend from the lower portion of sleeve 11 outward to the adjacent sleeves 17 and 20, respectively, so as to support them firmly and securely in their relative angular position to the central sleeve 11.
From the foregoing it will now be seen that there is herein provided an improved staging bracket which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.
As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to "be interpreted merely as illustrative, and not in a limiting sense.
I claim:
A staging bracket comprising a normally horizontal rectangular sleeve adapted to receive a horizontal beam of a staging, means for securing a beam in said sleeve, a pair of oppositely inclined rectangular sleeves secured to said normally horizontal sleeve on opposite sides thereof and extending in a direction transverse to the axis of said normally horizontal sleeve, both of said pair of sleeves being inclined in the same direction relative to the longitudinal axis of said first-mentioned sleeve whereby staging uprights are adapted to be inclined relative to a horizontal scaffolding support in a direction transverse to the axis of the horizontal support and in a direction 1 longitudinal to the longitudinal axis thereof with their upper and lower ends open and adapted to receive the opposite uprights of a staging A-frame, and means to secure said uprights in said inclined sleeves,
said means for securing the beam and the uprights comprising bosses on said sleeves having threaded bores therein, and set screws in said threaded bores,
4 said pair of oppositely inclined sleeves being offset relative to each other along the length of said normally horizontal sleeve and each being of a uniform dimension throughout its length to allow complete passage of a beam or an upright respectively therethrough.
